25GHz - 40GHz Circularly Phase Array Microstrip Patch Antenna for Millimeter Wave Communication

2020 International Journal of Engineering and Advanced Technology  
Millimeter wave technology will enable to provide high data rate. It is also expected to provide continuous good quality, low latency video. For high-resolution video, wireless communication will require huge bandwidth. The present 4G spectrum will be unable to meet the demand of each mobile user. To solve bandwidth shortage millimeter wave technology is consider. In this paper present a circularly phase array designed. It is operating in the 25GHz to 40GHz. To enhance bandwidth the array used

The designed used polyflon CuFlon(tm) low dielectric constant, Ɛr = 2.1 and tangential loss, δ = 0.00045 with height h = 1.6mm. The designed achieved 8.41dB gain. The array achieved good return loss, S11 bandwidth i.e. -11.83dB ≤ S11 ≤ -37.8dB (25GHz to 40GHz) and voltage standing wave ratio, VSWR ≤ 1.7 (25GHz to 40GHz).
