Abstract

In this letter, a compact ultrawideband planar inverted F‐L antenna with a tunable band‐notched response is presented. Tuning of the rejected frequency bands is realized by loading a variable capacitor on an embedded slot of the proposed antenna structure. The antenna exhibits a wide impedance bandwidth from 3.1 to 10.6 GHz with a good impedance matching (voltage standing wave ratio ≤ 2) and tunable broad range of band‐reject frequency (centre frequency from 3.2 to 6 GHz). To validate the theoretical model and design concept, the antenna prototype was fabricated and measured.
