Design and Performance Studies of an Elliptical Slot Circular Polarization Antenna for C-Band Wireless Applications

Abstract

A novel and subtle design of a circularly polarized microstrip line feed elliptical slot monopole antenna with an intention to use in C-Band (4-8 GHz) is proposed in this communication. Due to notable as well as remarkable performances, this small and compact antenna with ample applications in the arena of wireless communication upholds its strong position among the previous work of similar types. For designing and simulating the proposed antenna for exploration of its feasibility to use in the C-band wireless applications especially satellite-based communication system, CST MW studio is used. Different categories of calculations and performance studies have been performed while maintaining a suitable environment of free space for wireless communication. The antenna with overall dimension of 50 mm × 30 mm × 0.836 mm, where the substrate is used is Teflon and Copper is used as radiating patch as well as ground plane, is placed for evaluating its performance in respect of return loss, radiation and total efficiency, VSWR, gain, directivity, direction of surface current, axial ratio (AR) bandwidth, and reduction of cross polarization (XP). An impressive return loss (-41.7 dB) at the resonance frequency and suppression of XP of 33.50 dB have been accomplished with other marvelous results.
