Parametric Analysis of Single Element U Slot Microstrip Antenna

In wireless communication system antennas are the most important element for creating communication link between source and destination. Microsrtip antennas are used for mobile and other satellite communication application because of their light weight, low power handling capacity and low profile. The modern mobile communication system requires high gain, wide bandwidth and minimal size antennas that are capable of providing better performance over a wide range of frequency spectrum. This requirement leads to the design of microsrtip patch array antenna. This paper proposes the parametric analysis of single element U slot MSA. Low dielectric constant substrates are generally preferred for maximum radiation. Thus it prefers FR4 as a dielectric substrate. Desired patch antenna design is simulated by using high frequency simulation software and patch antenna is designed as per requirement. Antenna dimensions such as Length (L), Width (W), and substrate dielectric constant and parameters like Return Loss, Gain, impedance and current distribution are calculated using CAD-FEKO. The antenna has been design to be operated in the range of 8-12GHz. Hence this antenna is highly suitable for X-band applications.
