38GHz Rectangular Microstrip Antenna with DGS for 5G Applications

the rectangular microstrip antenna with inset feed operating at 38GHz was designed and analyzed using Computer Simulation Technology CST software. The antenna has a relatively compact size, with Rogers Duroid 5880 as substrate material and dielectric constant 2.2 with a height of 0.208 mm. The dimensions of the Defected Ground Structure (DGS) and its position were implemented experimentally with the help of CST. The bandwidth of the microstrip antenna was limited so the purpose of (DSG) is to get a wider bandwidth with maintaining acceptable values of efficiency and return loss. The final values of antenna gain, bandwidth, efficiency, return loss, and VSWR, which have been obtained from the simulation are 6.85 dBi, 2.146 GHz, 95.4%, - 40.54 dB, and 1.02 respectively. This type of antennas can find applications in 5G within the mm-Wave band where it is necessary to maintain high rates of Gbps.
