Abstract

An ultra-compact four-port ultra-wideband (UWB) antenna with dual notches, which can reject the 5G (3.3-4.2 GHz, 4.8-5 GHz) and the WLAN (5.15-5.825 GHz), is designed. Four orthogonal antenna elements and some defected ground planes constitute the proposed antenna. A double T-shaped filter structure is employed on the radiation unit, which can generate a notch frequency band of 3.3-4.2 GHz. The complementary split resonant ring (CSRR) structure is created on the ground plane. It is intended to suppress the frequency band from 4.8 GHz to 6 GHz by adjusting the size and position of the slots. Finally, the measured -10 dB impedance bands are 4.2-4.8 GHz and 6.0-11.0 GHz. The isolation performance exceeds 17 dB across the operational bandwidth. Additionally, the ECC remains consistently below 0.06 (and below 0.01 within the 4.2-4.8 GHz and 6.0-11.0 GHz range). Furthermore, within the operational band, the efficiency exceeds 85%. The proposed antenna is applicable in civil communication, military, and medical fields.
