2017 2nd IEEE International Conference on Recent Trends in …, 2017•ieeexplore.ieee.orgThis paper presents dual band circularly polarized antenna for IRNSS applications. The
antenna is loaded by four mono-poles around petal shaped patch. Crossed slot are added
on patch to miniaturize the total size of patch. The antenna is fed using branch line coupler.
Optimized dimension of antenna is 0.44 λ 0× 0.44 λ 0× 0.08 λ 0. Using this antenna we
obtained 3-dB Axial Ratio (AR) bandwidth of 31.6%, Also 34.33% impedance bandwidth
with SWR≤ 2 is achieved.
