Abstract
A compact U-Shaped antenna was proposed in this paper. The antenna is designed with dimension of 30*44*1.8 mm. The proposed antenna is used to improvement the ground stub. The antenna works in the various band of Wi-Fi, Wi-Max, WLAN, Wireless Communication and Satellite communication applications. The proposed structure having FR4 dielectric substrate with 4.2 relative permittivity and the loss tangent of 0.0025. The gain of the proposed antenna is 5.82 dB and 6.82 dB in the lower band and upper band of frequencies. The U-Shaped structure antenna operating at various bands 1.8 GHz to 2.5 GHz and 3.5 GHz to 4.5 GHz for wireless applications. The VSWR of the proposed structure is 1.4 and 1.8 respectively. The bandwidth is used to operate the U-Shaped structure is 900/1800 MHz. The reflection coefficient of the proposed structure is observed for the range of −7.08 dB and −14.00 dB. The performance parameters of the proposed structure such as good return loss, high gain, high bandwidth and good radiation pattern in nature.
