A Dual-Band (38 – 60 GHz) Antenna Designed for Millimeter Wave Wireless Communication Systems

摘要

In this paper, a compact dual band microstrip patch antenna is proposed for fifth generation (5G) wireless applications. This novel dual band antenna operates at the 38 and 60 GHz bands with a bandwidth around the two center frequencies (38/60 GHz) of 700 MHz and 1 GHz, respectively. The antenna consists of a semi-circular patch containing a slot, in addition to the etched two circular drained patches with optimized positions and dimensions. Moreover, a slotted partial ground is added for performance enhancement and bandwidth adjustment. The proposed antenna achieves a good performance regarding the return loss, bandwidth as well as the radiation pattern. The minimum attained return losses are −35.2 for the 38 GHz band and −36.9 dB for the 60 GHz band, while maintaining a compact antenna size. The simulated radiation pattern conforms with that needed for 5G antenna operation.
