Abstract
A dual band circular polarized planar antenna with coplanar waveguide(CPW) feed is presented in this work. A quasi hexagonal stub is used along with an inverted E arm embedded in the ground inorder to produce two circular polarized resonating bands covering bluetooth, mobile satellite services and weather radar surveillance usable bands. The axial ratio bandwidth is further improved by introducing stair shaped modifications in the ground. The presented antenna has been designed and optimized on FR4 substrate of thickness 1.6mm. The simulated result shows that this antenna covers two bands (2.01GHz-2.26GHz) and (2.9GHz-3.1GHz) at VSWR ≤ 2 and AR ≤ 3dB. © 2018 IEEE.
