Abstract

Microstrip patch antennas (MSPAs) have gained significant popularity due to their compact size, ease of fabrication, low cost, lightweight construction, and compatibility with planar and non-planar surfaces. The aim is to identify the optimal substrate for a designed MSPA by comparing the performance of six different substrates. Accordingly, both rectangular MSPA and circular MSPA (CMSPA) have been developed and simulated by using six different substrates: FR4 Glass Epoxy, ROGERS DT5880, ROGERS 4003C, Teflon, Arlon AD300A, and Alumina with thickness of 1.6 mm and 1 mm. Rectangular and CMSPAs have been fabricated and measured to verify the effects of the substrates. The proposed antenna is designed to achieve resonance at the target frequency of 5.8 GHz. This study offers valuable insights into the performance of MSPAs with various substrates, thereby assisting researchers in selecting the most appropriate materials for their designs.
