A Low-Profile, Dual-Band Frequency Reconfigurable Antenna for 5G/WLAN/Wi-MAX Applications

In this paper, a PIN diode is employed for frequency reconfiguration. An antenna is operating between 2.57 - 3.52 GHz and 4.89 - 6.18 GHz, it suits Wi-MAX (3.3 GHz), WLAN (5030 - 5990 MHz), and n46 (5150 - 5925 MHz) 5G bands when the diode is ON, and WLAN/n46 bands when OFF. The antenna achieves over 85% radiation efficiency and favorable gain, establishing it as a strong contender for 5G/WLAN/Wi-MAX applications.
