Crescent Shape Microstrip Antenna for Dual polarized Multi-band Response

Abstract

Novel design of multi-band Crescent shape microstrip antenna is proposed. Modifications in equivalent circular patch yields new resonant modes nearer to the TM11 and TM21 modes in circular patch that gives four band frequency response showing dual polarizations. Proposed design gives 1 to 1.5% of bandwidth at each frequency with broadside radiation pattern. The resonance frequency equation by defining the resonant length at each mode in the Crescent shape patch, is proposed. The frequency calculated using the same agrees closely with simulated result. The air suspended design of crescent shape patch is presented which yields co-polar peak gain of above 1.5 dBi.

“…The centers of each body are placed on the same axis, but C 2 is shifted from C 1 . In Deshmukh and Verma (2019), 13 a parametric study was presented that estimated the dimensions of the CS needed to achieve the different resonance modes required for CP radiation. A prime advantage of the CS is that it can yield wideband operation due to resonance frequencies corresponding to multiple resonant modes 14,15 …”
