The Wi-Fi and WLAN provides wide range of wireless connections between devices such as computers, mobile phones and other devices for transferring data from one device to another. Now-a-days wireless devices had become a part of human life and this makes the wireless device to have a fast and better performance. Data transfer over an unguided media for a shorter distance communication called Bluetooth and over a longer distance called Wi-Fi is used with the frequency range of 2.4 to 2.485 GHz. In order to transmit data through an unguided media, antenna is required and the major constraints in wireless communication applications can be overcome by using microstrip patch antenna. Antennas plays a vital role in wireless communications for signal transfer which had to be compatible with the emergence of new standards [1]. The design and modeling of microstrip patch antenna elements and arrays had been seen a rapid development since 1980s due to the advantages like reduction in size, weight, cost and easy integration with active device to form a reconfigurable configuration [2]. Islam et. al. studied the performance of microstrip patch antennas for different material which had different dielectric permittivity for WiMAX applications [3]. The microstrip patch antenna design used in communication system have to overcome the drawbacks which includeslow gain, minimum bandwidth, gives rise to surface waves and radiation from the edges[4] [5]. The antenna consists of a radiation conductor patch above the dielectric substrate and a conductor (ground) below the substrate. The conducting material is generally gold or copper, where copper being a lossy material. The two methods of feeding the RF power to the antenna are contacting and non-contacting techniques where contacting method uses either probe feed or microstrip line where as the later uses proximity feeding or aperture feeding [6] [7]. An artificial neural network based microstrip patch antenna was designed for 2.45 GHz Industrial, Scientific and Medical (ISM) band applications which resulted in good reflection coefficient at the resonant frequency [8]. A multiband patch antenna proposed by Mahabub et. al. [9] operates under 2.4 GHz Wi-Fi, 7.8 GHz WiMAX and 33.5 GHz 5G communications applications showed high directivity and low Voltage Standing Wave Ratio (VSWR). This paper shows the design and analysis of inset fed microstrip patch antenna to be operated at 2.4GHz for wireless communication applications.
