A Compact Multiband Microstrip Antenna Design for 5G IOT and Satellite Communication Applications

In this study, a microstrip patch antenna was designed to enable complete coverage of satellite communication. The antenna is capable of covering almost four bands, including S, C, Ka, and Q/V bands. The bandwidth achieved for these bands is relatively large, with the maximum bandwidth of 15.6 GHz achieved at the Q/V band and 11.4 GHz achieved at the Ka band. In the microwave range, the S and C bands have a bandwidth of 2.1 GHz, which is considerable. The antenna achieves a maximum gain of 9.1 dBi at the Q/V band. Moreover, the efficiency of the antenna is remarkably high, with almost 99% efficiency achieved at the Ka band and above 90% efficiency achieved for other bands. The proposed antenna also has a good radiation pattern, and it is considered a suitable contender for the satellite communication system and 5G IOT applications.
