Performance Analysis of Square Shaped Microstrip Patch Antenna for S Band Application Pradeep Kumar Sharma1, Ritesh Saraswat2 Sr.Assistant Professor1, Associate Professor2, Department of ECE, Jodhpur Institute of Engineering & Technology, Mogra, Jodhpur, India, ABSTRACT Microstrip patch antenna is a narrowband and wide beam antenna which is generally fabricated by etching process in which the antenna element pattern will be bonded with metal trace to an insulating dielectric surface. For forming the ground plane on the other side, there will be continuous metal layer bonded with substrate. Microstrip antenna has square, rectangular, circular, elliptical and annular ring which are general shapes. In this research we have studied the effect Dielectric constant (εr) on the Radiation parameters of Bandwidth and Return Loss. For this purpose, CST platform has been used. The frequency band 2-4 GHz is assigned as S band which is used in the applications such as satellite, Wi-Fi, Bluetooth ,cellular phones etc. The proposed method has been applied on the square Microstrip patch antenna and conclusions have been drawn on the frequency of 3.055 GHz on which the antenna has been tuned. The results have been shown for the antenna in simulated manner as well as practical results. The practical results which have been obtained by vector network analyzer are not calibrated. Microstrip antennas are attractive due to their light weight, conformability and low cost. A microstrip patch antenna consists of conducting patch on a ground plane which is separated by dielectric substrate. But this concept was undeveloped till the revolution in electronic circuit miniaturization and large-scale integration in 1970. After that there were so many authors who have described the radiation from the ground plane by a dielectric substrate for different configurations. The work which was done by Munson on micro strip antennas for use as a low profile flush mounted antennas on rockets and missiles represented that this was a practical concept for use in many antenna system problems. After that various mathematical models were developed for this antenna and its applications were realized to many other fields. Its importance can be seen by counting the number of papers, articles published in the journals for the last ten years show the importance gained by this antenna. Other configurations are complex to analyze and require heavy numerical computations together with the mathematical calculations. A microstrip antenna is characterized by its Length, Width, Input impedance, Gain, VSWR and radiation patterns. The micro strip antennas are considered as the present day antenna designer’s choice. We consider low dielectric constant substrates for the maximum radiation. The conducting patch can be given any shape but there are rectangular and circular configurations which are the most commonly used configuration.
