Abstract

In this paper, a broadband 2-D phased array based on 16 identical planar quasi-Yagi elements is presented. Firstly, a modified quasi-Yagi antenna with wide beamwidth is developed. Then, by dividing the antenna “card” to independent elements, inserting a metal fence between front-back elements, which is as high as the antenna´s ground plane, the mutual coupling is mitigated. After constructed with Wilkinson power divider and T/R modules, a fully functional active phased array is implemented. Measured radiation patterns show that the X-band array prototype can scan ±30 degree across the whole X-band from 8GHz to 12GHz.
