<span>The fifth generation (5G) of telecommunications is an attractive application for many researchers during the last years. The 5G requires high date rate with low latency communication medium and patch antenna was used recently this application. In article a at 38 GHz proposed. This worked on enhancing gain Ka-Band reducing side lobes level (SLL) in radiation pattern. improved using r...

New optimized 2x2 slotted array antenna is designed using HFSS to operate at 28.1 GHz, RT6010 substrate with height of 1.6 mm, tangent loss 0.0023 and dielectric constant 10.2 overall dimension 12x12 mm 2 , for 5G mobile applications. The linear achieved a high gain 18.3 dB GHz 10 bandwidth 1.39 83.21% size reduction.

Abstract A transmissive metal unit working in the range of 18 GHz-29 GHz is designed this paper. This a three-layer circular slit with promising cross-polarization isolation properties. planar lens antenna center operating frequency 28 based on utilizing phase compensation algorithm. The numerical simulation results show that can improve gain horn from 22.9 dB to 25.6 dB, which effectively adva...

Bandwidth and gain enhancement of microstrip patch antennas (MPAs) is proposed using reflective metasurface (RMS) as a superstrate. Two different types of the RMS, namelythe double split-ring resonator (DSR) and double closed-ring resonator (DCR) are separately investigated. The two antenna prototypes were manufactured, measured and compared. The experimental results confirm that the RMS loaded...
