Analysis of a Low-Profile Reconfigurable Wideband L-shaped Printed Antenna for ۵G/ISM-Band Applications

A low-profile frequency reconfigurable L-shaped printed antenna operating in microwave frequency band is presented in this article. The proposed antenna is fabricated on FR۴ material having δ of ۰.۰۲, relative permittivity of ۴.۴ and thickness of ۱.۶ mm. HSCH ۳۴۸۶ PIN diode is inserted in between the feed line and the L-shaped structure for switching. The proposed antenna is resonating at ۳.۵ GHz and ۶.۶ GHz and offered an impedance bandwidth of ۰.۹ GHz and ۳.۵ GHz. Voltage standing wave ratio of the antenna is less than ۱.۵ at both the resonating frequencies. Efficiency of the designed antenna is ۸۷% and ۳ dBi gain of the antenna is ۴.۶۱ dBi. The proposed antenna is simulated by utilizing finite element method tool Ansoft HFSS v۱۳ and the simulated results are experimentally validated. Due to its compact size the proposed antenna can be used for ۵G-sub-۶GHz and ISM band, X-band satellite communication applications.
