摘要：
A probe-fed patch antenna with 180 degrees ring hybrid is proposed for in-band full-duplex applications. The proposed antenna consists of two substrate layers with the ground plane in between. A patch is printed on one substrate opposite the ground, and a ring hybrid is printed on a second substrate, which is designed to separate the receiving and transmitting signals, producing high isolation between the two. Simulated and fabricated prototype results show isolation of -58 dB covering the Industrial, Scientific and Medical (ISM) band of 2.4-2.5 GHz with a centre frequency of 2.45 GHz.
