Ultra Wide Band Dual-Feed Millimeter Wave Antenna

Faster data throughput and low latency are the main development agenda in modern communication system. In addition to higher modulation rate, mm Wave also can achieve high data throughput, low latency and significance of results. In this paper, Ultra Wide Band Dual polarized Antenna is designed for post 5th Generation Wireless communications that can support n257 (25.6GHZ-29.5GHz), n258 (24.25GHZ-27.5GHz), n260(37GHz-40GHz) and n261 (27.5GHz-28.35GHz). Ultra wideband is limited to have higher antenna gain, however, antenna array design can improve antenna gain and radiation pattern, one dual feed antenna can provide two antenna radiation patterns,Antenna gain degradation by the tolerance of material can be improved by high power laser beam. The antenna covers 24.24 GHż29.5 GHz and 37 GHz~40 GHz and has a broad bandwidth both in low and high band frequency. The peak gain of high band frequency is 5.5dB and the peak gain of low band is 5.1 dB. The dimension of the antenna element can achieve as small size as of 10 mm x 10mm x1.844mm, and the size is suitable for mm Wave repeater application and mobile phone with mm Wave function.
