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
