摘要

本文提出了一种大频率比的双频天线。通过微波贴片天线与毫米波天线阵列的垂直组合，实现了高孔径复用效率的一体化设计。在设计中，毫米波天线置于微波天线之上，采用微波天线的辐射贴片作为毫米波天线地。通过微波贴片天线的短柱，使微波和毫米波天线共用地面。为了演示这一想法，以3.5 GHz和26 GHz两个5G通信关键频段的设计为例。在3.5 GHz和26 GHz频段分别实现14%的带宽和7.4 dBi增益，8%的带宽和16 dBi增益。

A Dual-band Shared-Aperture Antenna With Large Frequency Ratio for 5G Applications

In this paper, a dual-band antenna with large frequency ratio is proposed. By vertically combing a microwave patch antenna and a millimeter-wave (MMW) antenna array, an integrated design with high aperture reuse efficiency is obtained. In the design, the MMW antenna is placed above the microwave antenna and adopts the radiation patch of the microwave antenna as the MMW antenna ground. Through a shorting post of the microwave patch antenna, the microwave and MMW antenna share the common ground. To demonstrate the idea, a design at 3.5 GHz and 26 GHz which are two key bands for 5G communications is presented as an example. 14% bandwidth with 7.4 dBi gain and 8% bandwidth with 16 dBi gain are achieved at 3.5 GHz and 26 GHz band respectively.
