摘要

更快的数据吞吐量和低延迟是现代通信系统的主要发展方向。除了更高的调制速率外,毫米波还可以实现高数据吞吐量、低延迟和显著性的结果。本文针对后五代无线通信设计了超宽带双极化天线,可支持n257 (25.6GHZ-29.5GHz)、n258 (24.25GHZ-27.5GHz)、n260(37GHz-40GHz)和n261 (27.5GHz-28.35GHz)。超宽带受限于具有较高的天线增益,但天线阵列设计可以改善天线增益和辐射方向图,一个双馈天线可以提供两种天线辐射方向图,高功率激光束可以改善材料公差导致的天线增益退化。该天线覆盖24.24 GHż29.5 GHz和37 GHz~40 GHz,在低频段和高频段都具有较宽的带宽。高频段的峰值增益为5.5dB,低频段的峰值增益为5.1 dB。天线元件的尺寸可小至10mm × 10mm × 1.844mm,尺寸适用于毫米波中继器应用和具有毫米波功能的手机。

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.
