Abstract
In this paper, a rectangular microstrip antenna has been designed. The design has been implemented with a defected ground surface (DGS) to obtain the desired gain and reflection coefficient at both the frequencies 2.45 and 3.75 GHz. In the proposed design, a microstrip patch antenna having an Inset Fed giving the dual-band characteristics is implemented using FR-4 as the substrate for the designed simple microstrip patch antenna, which has got a dielectric constant of 4.3. The designed microstrip patch antenna was simulated on computer simulation technology (CST), and the desired results were obtained. Four “L”-shaped slots have been made on the surface of the patch leading to an increase in the density of the current on the surface of the simple microstrip patch antenna which also led to multiband characteristics, thus improving the results. The S11 parameters were found to be below −10 dB mark for both the frequencies. The gain obtained at 2.45 and 3.75 GHz was found to be 4.1 dB and 3.57 dB, respectively. The design proposed in this paper has been found to be useful for power transmission applications, such as wireless headphones, cordless phones, keyless vehicle locks, and Bluetooth.
