Abstract:

This paper implements an in-band full-duplex (IBFD) bistatic microstrip patch antenna with a U-slot for dual-band wireless communication. Two inset feed U-slot microstrip patch antennas, for transmitter (Tx) and receiver (Rx), are placed orthogonally, separated by a small distance, and a set of shorting vias are inserted along the Rx antenna's radiating edge in-between the antennas. In this compact layout, top-to-bottom connected vias are used to make the antenna a short-circuited quarter-wave resonator and minimize the mutual coupling between the antennas. Tx and Rx antennas have an isolation of −44 dB and −24 dB at 2.12 GHz and 5.28 GHz, respectively. Tx antenna has radiation directivity of 5.19 dBi and 6.33 dBi at 2.12 GHz and 5.28 GHz, respectively. The gain of the Rx antenna in the direction of maximum radiation is 4.91 dBi and 4.42 dBi at 2.12 GHz and 5.28 GHz, respectively.

I. Introduction

A contemporary communication system consists of terminals, such as base stations, relays, and mobile devices. These terminals function in either half-duplex mode or out-of-band full-duplex mode, where they can only transmit or receive data at distinct times. Otherwise, they may send and receive data simultaneously, utilizing multiple frequency bands. Our wireless spectrum is limited, but the demand for it is increasing rapidly due to the growth in the use of wireless devices. Systems with better spectrum efficiency, such as in-band full-duplex (IBFD), may assist in resolving this issue. It can transmit and receive data simultaneously at a single frequency at the same time, resulting in a twofold increase in spectral efficiency. The primary challenge of IBFD antennas is self-interference (SI). SI refers to the undesired signal that is sent by the transmitting (Tx) port of the IBFD terminal and interrupts the desired signal at the receiver (Rx) port [1].
