Abstract: ABSTRACT This article proposes a novel metasurface patch antenna with characteristics of metasurface and broadband for in‐band full‐duplex applications, which is configured with a parasitic metasurface, a square patch, two separated feeding networks for transmitting and receiving ports (Tx and Rx), and a square ground. Two feeding networks consist of an antisymmetric L‐shaped probe feeding structure for Rx and a double F‐shaped feeding structure with a 3 dB/180° hybrid coupler for the Tx port to achieve ±45° polarization and significantly enhanced isolation between the ports. Most importantly, the proposed parasitic metasurface realizes good impedance matching and improves realized gain. Therefore, the proposed antenna attains a −10 dB of overlapped bandwidth of 52.6% through 1.7 to 2.7 GHz with a high isolation of over 41.5 dB. Additionally, the measured gains are 8.9 ± 1.1 dBi for the Rx port and 7.4 ± 0.9 dBi for the Tx port, respectively. These characteristic data all support that the proposed antenna will play an essential role in IBFD applications.
