Abstract
In this paper, a compact two-port antenna consisting of an open-ended slot loaded with shorting pins and a T-shaped stub is presented. The beak-shaped two-port antenna radiators enhance the antenna bandwidth and electrical length. The two inverted L-shaped open-ended slots form an effective capacitance and an inductance, resulting in a dual-operating band. The T-shaped stub improves electrical height and impedance matching to ground, while the combination of the T-shape and open-ended slots provides a dual-band response and improves isolation by up to 8 dB. Shorting pins connected to the ground show inductive behavior that improves isolation by up to 6 and 4 dB for the low- and high-frequency bands. The two-port antenna exhibits more than 20 dB of isolation with only 2 mm of edge-to-edge distance of the antenna element. The two-port antenna operates in dual frequencies from 4.1 GHz to 4.6 GHz and from 5.55 GHz to 6 GHz, and the 32 mm × 26.5 mm size makes it suitable for 5G and WLAN/ISM applications.
