Title A name given to the resource Wideband microstrip comb-line linear array antenna using stubbed-element technique for high sidelobe suppression Creator An entity primarily responsible for making the resource Samuel Afoakwa, Young-Bae Jung Description An account of the resource This paper presents a novel wideband microstrip comb-line linear array antenna using end feeding developed in the millimeter-wave. The proposed antenna is designed for 28 GHz and has 12 elements. The reflection-canceling slit structure technique is adopted to develop a broadside beam with low reflections at the input. The proposed array is designed using stub-studded radiating elements that create more resonances to broaden the impedance bandwidth. The structure is a novel comb-line linear array antenna with stub-studded radiating elements and was developed by applying stubs to eight of the radiating elements of the array to increase the input impedance bandwidth. This helps to attain a wideband linear array antenna on a single dielectric substrate, which conventionally has a narrow bandwidth. The input impedance bandwidth is from 23.5 to 33.11 GHz, which is equivalent to a bandwidth of 33.95 … Publisher An entity responsible for making the resource available IEEE Date A point or period of time associated with an event in the lifecycle of the resource 2017 Source A related resource from which the described resource is derived https://scholar.google.com/citations?view_op=view_citation&hl=en&user=QRyINJYAAAAJ&citation_for_view=QRyINJYAAAAJ:u-x6o8ySG0sC Language A language of the resource English https://www.repository.gctu.edu.gh/files/original/f3fbb435c136f77f169dcfb4fad8f4fd.pdf 367a8ad1f1281dbca72128d96f772415 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Omnidirectional dipole antenna with wideband and low gain variation Creator An entity primarily responsible for making the resource Samuel Afoakwa, Young‐Bae Jung Description An account of the resource This study presents an omnidirectional dipole antenna with wideband and low gain variation in the horizontal plane. The antenna is made up of two driven dipoles and two parasitic dipoles placed symmetrically on both sides of a central ground plane. The driven dipole is made up of two planar arms printed on both sides of the substrate. Two small slits on both sides of the driven dipole, a large centrally placed slit in the driven dipole, extensions on both sides of the driven dipole with different dimensions, and parasitic dipoles are introduced to greatly enhance the bandwidth and also attain a low gain variation. The fabricated antenna achieves a wide impedance bandwidth of 105.5% (1.36–4.4 GHz) for S11 ≤ −10 dB, and an average gain of 4.14 dBi with a low gain variation of 2 dB. The antenna may find applications in 2G/3G/LTE frequency bands.

An Android application based on fuzzy logic rules and fuzzy inference was created in this research. In Ghana, the service assesses the symptoms of diseases. The android application is built with the Support Vector Machine learning technique, with the aim of improving the model’s accuracy and performance. Natural Language Processing is often used by the machine to achieve the conversational style of asking the users for their symptoms. People can spend less time in hospitals and get low-cost or free care by using this technique, which is mainly used in Ghana’s rural areas.

Title A name given to the resource Frequency Splitting Elimination in a multi-coil power transfer system Creator An entity primarily responsible for making the resource Samuel Afoakwa, Young-Bae Jung Description An account of the resource A multiple transmitter coil wireless power transfer system that eliminates the frequency splitting effect as a result of overcoupling between very close transmitter coils is proposed. The use of coils of different sizes in the transmitter array is proposed in order to eliminate the splitting of the magnetic field produced by the transmitters. This is done by designing three different multi-coil transmitter arrays, each with five transmitter coils with a single receiver coil placed 40 cm from the transmitters. The first array is designed with coils of the same size. The second and third arrays are designed with coils of smaller sizes placed between larger size coils. The performance of the three arrays is compared by considering the scattering parameters at the receiver coil. It is shown that using smaller coil sizes between larger coils causes uniform coupling in the multiple transmitter array, resulting in suppression and subsequent … Publisher An entity responsible for making the resource available IEEE Date A point or period of time associated with an event in the lifecycle of the resource 2020 Source A related resource from which the described resource is derived https://scholar.google.com/citations?view_op=view_citation&hl=en&user=QRyINJYAAAAJ&citation_for_view=QRyINJYAAAAJ:9yKSN-GCB0IC Language A language of the resource English Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The proposed antenna in this paper is a rectangular patch with two large slots created in its radiating surface and extension on its edges for wider bandwidth and better matching. It employs a modified ground plane that uses coupling to achieve low return loss. CST microwave studio software was used for the simulation and optimization. The characteristics and simulated results are analyzed before the prototype structure is fabricated on an FR-4 substrate. A monopole planar antenna with total dimensions of 185× 45× 1.6 mm3 with an omnidirectional radiation pattern in the H-plane is fabricated and the results are presented. The antenna has high impedance bandwidth characteristics with operating frequency at-10 dB return loss from 470 MHz to 900 MHz and about 63% bandwidth efficiency. It has a VSWR ratio of less than 2. The significance of the various sections of the antenna together with the simulated and fabricated results is presented.

Title A name given to the resource Efficiency Enhancement in a Multi-coil Wireless Power Transfer System Creator An entity primarily responsible for making the resource Samuel Afoakwa, Kyei Anim, Young-Bae Jung Description An account of the resource Wireless power transfer technology via magnetic resonance coupling now has significant interest in industry and research with many applications. This paper proposes a linear multiple transmitter coil array (5 coils) for wireless power transfer for added gain and hence higher transfer efficiency in comparison to a single transmitter coil. The frequency splitting effect as a result of the coupling between the resonant transmitter coils due to their close proximity is shown to reduce the transfer efficiency to a receiver. The effect of the array spacing on splitting effect suppression is verified. It is shown that the splitting effect is sup-pressed as the distance between the coils is increased leading to a higher received signal and hence higher efficiency. Proposed horizontal displacement of the middle transmitter coils (2nd and 4th coils) in the coil array is shown to suppress frequency splitting. To further suppress the splitting effect due to the magnetic coupling between the transmitter coils, a multiple transmitter array is proposed with different coil turns. Thus it is shown that designing the multiple coil array with mixed number of coil turns (the 2nd and 4th coils are designed to have different number of turns as compared to the other three coils) causes uniform coupling among the coils reducing and eventually eliminating the splitting effect. Also to increase the efficiency at the receiver coil, displaced stacked coils are introduced on top of the coil array. The pro-posed stacked coil array is demonstrated to improve the transfer efficiency. Using the techniques, the proposed linear array structure achieves a transfer efficiency of 36.9% for a receiver coil at the boresight of the … Date A point or period of time associated with an event in the lifecycle of the resource 2021 Source A related resource from which the described resource is derived https://scholar.google.com/citations?view_op=view_citation&hl=en&user=QRyINJYAAAAJ&citation_for_view=QRyINJYAAAAJ:d1gkVwhDpl0C Language A language of the resource English Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
