In future 5G the requirement of bandwidth in cellular mobile communication will be huge for providing high data rate, uninterrupted high-quality, low latency video, multimedia application and high-resolution video etc. And the number of the cellular mobile user is growing tremendously. The present fourth generation (4G) Long Term Evolution (LTE) cellular bandwidth will unable to meet the future bandwidth requirement. To easily allow wider bandwidth allocations millimeter wave technology is considered to solve the problem of bandwidth shortage. This paper presents an inset fed rectangular patch antenna and its 2x2 element circular phase array antenna operating in the millimeter wave band (31GHz). The array has designed with an edge coupled parasitic patch arrangement, a single feeding port and a rotation feeding line. The designed array used single layer structure instead of low temperature co-fired ceramic (LTCC) technology which further helps in achieving low cost with simple fabrication technique. The designed enhanced the bandwidth and gain with CPW feed. The design antenna array achieved 32% (28GHz−35GHz) bandwidth, maintaining good return loss (−14.10dB ≤ 􀜵􀬵􀬵 ≤ −52.57dB). The designed antenna array has a good return loss S11, -52.57dB at 32.57GHz and VSWR ≤ 1.8 (28GHz-35GHz). The designed array will be suitable for the future millimeter-wave wireless communication system.
