CRESCENT SHAPE MICROSTRIP ANTENNA FOR DUAL POLARIZED MULTI-BAND RESPONSE
Keywords:Circular microstrip antenna, Crescent shape microstrip antenna, Multi-band microstrip antenna, Dual polarization
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 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.
