Abstract
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.
