Abstract
This article presents a compact antenna design of overall size 38.4 mm × 46.8 mm having square shape and an inverted F-shape notches. The proposed antenna of single band is resonating between 1.69 and 2.91 GHz at two frequencies 1.98 GHz and 2.56 GHz. The proposed structure of antenna design has three square shape notches at corner and an inverted F-shape notch. The loading of notches inside radiating patch increases the effective current path. Due to increase of current path, radiation of antenna increases and large bandwidth is obtained. The reflection coefficient and impedance bandwidth both are increases gradually by loading different notches in radiating patch. Parametric investigation is also performed to figure out the effect of different parameters. The proposed antenna shows fractional bandwidth of 53.04% (1220 MHz) resonating at frequencies 1.98 GHz and 2.56 GHz with good reflection coefficient of − 27.14 dB and − 21.49 dB respectively. To validate the antenna performance, the simulated results for the proposed antenna are compared with measurements taken with fabricated antenna. The operating frequency band of proposed antenna is useful in L and S-band for PCS (1.85–1.99 GHz), UMTS (1.92–2.17 GHz), WLAN (2.4–2.484 GHz), and WiMAX (2.5–2.69 GHz). A stable peak gain of 2.9–3.84 dB and antenna efficiency of 81–91% is observed in entire resonating band.
