“…The antenna design stage deals with the construction of the various microstrip antenna shapes in MATLAB's Antenna Toolbox using the design function with a specified [33]. The ideal antenna testing stage involves determining the critical antenna characteristics such as antenna gain, efficiency, impedance, return loss, VSWR, beamwidth, and the 3D radiation pattern for each antenna [34].…”

In this comparative study, seven different microstrip antenna shapes, including rectangular, elliptical, triangular, inset fed, H-notch, and E-notch, were observed and analyzed, focusing on their suitability for global positioning system (GPS) application in microsatellites. To enable meaningful comparison, the study utilized the optimal resonant frequency in GPS applications, which is 1.57542 GHz. All the antenna designs have been generated using MATLAB’s Antenna Toolbox and are 100% efficient under ideal conditions with zero polarization loss, which is assumed in the link budget analysis. The results show that each antenna shape has been found to offer distinct advantages and limitations. Along with this, the circular and elliptical patch antenna presented a well-balanced performance, which is suitable for GPS applications. However, the elliptical shape falls behind the circular shape, which was determined to be the most optimal choice for GPS application, providing excellent isotropic antenna gain, return loss, voltage standing wave ratio (VSWR), and strong link budget analysis results.

“…The study aims to determine enhanced gain and reduced |S11| levels across different frequencies in the Industrial, Scientific, and Medical (ISM) band. The EMSPA is designed and simulated using various software tools, including MATLAB, to estimate performance characteristics such as s-parameters, voltage standing wave ratio, EH fields, radiation pattern, current distribution, gain, elevation, and azimuthal radiation patterns [10]. A UHF-RFID circularly polarized reader antenna is presented, with an impedance bandwidth of 880-960 MHz and a voltage standing wave ratio less than 1.5 [11].…”

This study focuses on the development, simulation, and practical validation of a metal-only microstrip patch antenna and its array designed to increase gain. The antenna is specifically designed to meet the growing demand for reliable and efficient RFID systems in various fields, such as asset tracking, inventory management, and smart logistics. Our design utilizes a truncated patch with an air substrate to achieve high gain and circular polarization. The antenna's dimensions measure 468 × 188 × 31 mm³ and deliver impressive performance metrics, boasting a return loss |S11| of -18.21 dB and an estimated gain exceeding 10.6 dBi. These figures compare favorably with the simulated results, which indicate an |S11| of -20.8 dB and a total gain of 11.2 dBi. Our microstrip antenna array demonstrated consistent Circular Polarization quality throughout the radiation angle, with an Axial Ratio of less than 3 dB. This antenna has emerged as a compelling solution for UHF-band RFID technology to meet the demands of various real-world applications.
