A Study on Compact Microstrip Antenna Design for Advanced Wireless Applications

A study on compact antennas for fifth generation wireless communication, which operates at K and Ka band frequencies are discussed in this paper. The antenna miniaturization is achieved by making simple rectangular slots on the patch. The overall size of the antenna is 6.3 mm ×6.0 mm. The proposed patch size is 4.6mm×3.6 mm, which means a notable miniaturization ratio has been achieved. The discussed antennas are designed on RogersRT5880 substrate considering a thickness of 0.787mm. The maximum gain of 7.43 dB at 24.1GHz is achieved for antenna I. The presented antennas are designed and simulated using High Frequency Structure Simulator (HFSS).
