A probe‐fed patch antenna with 180° 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.
