Abstract
A dual-band high-performance circular patch microstrip antenna for future 5th generation (5G) of mobile communication is proposed. The designed antenna has a ring-shaped Defected Ground Structure (DGS) in the ground plane. The proposed antenna operates at 28GHz (27.68GHz – 28.55GHz, 3.10%), which is a proposed frequency for 5G. A ring-shaped Defected Ground Structure is suitably inserted in the ground plane resulting in an additional frequency band at 38GHz (37.13GHz – 38.20GHz, 2.81%). The gain of the antenna at 28GHz is 6.87dBi and 4.17dBi at 38GHz. The size of the proposed antenna is 7.23mm x 7.23mm. The introduction of Defected Ground Structure also improved the antenna performance. Furthermore, different parameters of the proposed antenna are varied, studied and discussed in detail to observe its effects on the antenna performance.
