A T-Shaped Feed Single-Band Miniaturized Antenna Suitable for 5G Applications

A miniaturized single-band antenna element suitable for 5G applications is proposed. The proposed antenna element innovatively integrates a T-shaped feed structure with a compact meandered loop radiating element. It features two resonant points at 3.4 GHz and 3.55 GHz, with the overlapping resonant bands exhibiting a wide -6dB impedance bandwidth of 360 MHz (3.27 GHz-3.63 GHz), fully meeting the application requirements of the 3300 MHz to 3600 MHz band. Additionally, the efficiency of the antenna element is approximately 50-68%. The work also presents results such as the antenna S-parameters, voltage standing wave ratio (VSWR), current distribution, and far-field radiation patterns.
