A novel and simple design of circularly polarized sectored annular ring microstrip antenna with coplanar and concentric circular microstrip antenna is presented. The proposed antenna has single microstrip line feed with defected ground structure. Simulation analysis has been carried out using Ansoft High Frequency Structure Simulator (HFSSTM) software and measurement is carried out using the AgilentTM Vector Network Analyser (N5230A:PNA‐L). Parametric analysis of return loss and axial ratio versus frequency for different physical parameter of antenna has been studied. Experimental results of the proposed antenna show the 34.61% impedance bandwidth and 8.08% axial ratio bandwidth at 2.6 GHz center frequency with 6.96 dB peak gain. Simulated results are in good agreement with measured results. Due to low profile and simple geometry, it can be applicable for S‐band application effectively as wireless LAN, Wi‐Fi, Bluetooth, Zig‐Bee, and radio frequency identification antennas. © 2015 Wiley Periodicals, Inc.
