Circularly Polarized Coaxial Feed Microstrip Patch Antenna
Journal Title: The International Journal of Technological Exploration and Learning - Year 2013, Vol 2, Issue 5
Abstract
this paper presents a novel compact, single feed, rectangular circularly polarized, Micro strip antenna for RADAR communication, point to point and multipoint wireless communication. The proposed antenna fed by 50Ω impedance thin micro strip line occupies a compact volume of 34x34x0.508 mm3.Proposed design shows multiband characteristics for different center frequencies, and antenna offers a 2:1 VSWR bandwidth of 8.9%(10.047-10.906) at S11≤ -10 dB at center frequency of 10.2 GHz. Circular polarization is brought about by embedding a slit and by chamfering the diagonal edges of the patch. The software used for the simulation is the CST Microwave Studio which is an analytical tool that provides an accurate 3D EM simulation results for high frequency design.
