| Title: | Wideband Microstrip Patch Antennas with Transverse Electric Modes |
| Abstract: | A wideband microstrip patch antenna, exciting the fundamental transverse electric (TE) mode, is investigated. The excitation of the TE mode is facilitated through replacing both of the patch and ground plane of a conventional microstrip antenna with artificial magnetic conductors (AMC), consisting of unipolar compact photonic bandgap (UC-PBG) unit cells. The AMC patch and the ground plane of this antenna behave as magnetic conductors within the bandgap region of the unit cells. Similar to conventional patch antennas, it is shown that by cutting a U-shaped slot in the AMC patch, wideband characteristics are realized. The antenna shows a 40% impedance bandwidth and operates at the TE10 mode. Moreover, the width of the patch is 1.75 times smaller than its length, reducing the overall size of the antenna by about 60%, compared with the conventional U-slot PEC antenna supporting the transverse magnetic (TM) mode. |

| Title: | Design of a New Wideband Single-Layer Reflective Metasurface Unit Cell for 5G-Communication |
| Abstract: | In this paper, a new single layer subwavelength unit cell is designed for reflective metasurface at 28 GHz suitable for 5G communication with linear phase response and wide bandwidth characteristics. The proposed unit cell is analyzed through Floquet mode analysis for two different sizes. The unit cell with conventional half-wavelength size (HWS) has achieved 590° phase range while the unit cell with a subwavelength size (SWS) of λ/3 has achieved exactly 360° phase range. It is observed that the unit cell with SWS provides linear phase response as compared to the unit cell with HWS. Since non-linear phase response may produce more phase errors on wide range of frequencies, so SWS unit cell with 360° phase range and linear phase response is more suitable option for wideband operation as compared to conventional HWS unit cell with more than 360° phase range. |
