Abstract
The modern wireless communication systems require large bandwidth, high gain and small size antenna's with the purpose of providing enhance the performance over a broad range of frequencies. Due to this requirement direct to design a Microstrip rectangular patch antenna. The proposed design of microstrip antenna is reported, which is increased the bandwidth of microstrip patch antenna by cutting part of slots on the radiating edge of the main rectangular patch. Once more L-shaped slot, which is gives better return loss and dual band by cutting slot on the rectangular antenna. For maximum radiation low dielectric constant are generally preferred. This proposed antenna used micristrip line feeding method. Using HFSS-14 simulation software I have analysis antenna parameters like Gain, Return loss, VSWR and Impedance. The aim of this paper is to increase the impedance, dual bandwidth and to maximize gain, thereby improving upon the performance of antenna. The proposed antenna achieved operating frequency range for without slot 9.192–9.822 GHz with VSWR less than 2 and for with slot 8.659–8.872 GHz and 10.857–11.125GHz with also VSWR less than 2. And also it exhibits BW is 0.63 GHz with gain 5.78 dBi for 9.6 GHz and BW are 0.213 GHz, 0.268 GHz with gain 5.65 dBi, 6.26 dBi for 8.8 GHz, 11GHz frequency respectively.
