A Compact Wideband Circularly Polarized Monopole Antenna for Bluetooth/ WLAN and WiMAX Applications
In this paper, a compact wideband circularly polarized (CP) printed monopole antenna is designed and demonstrated. The proposed antenna geometry comprises a monopole having two orthogonal stubs and a defected ground plane. Upon optimization of both the stubs present in top plane and the slot present in the ground plane, a wideband right-hand circularly polarized (RHCP) radiation is achieved. The geometry exhibits a 10-dB impedance bandwidth of 3.17 GHz (2.08 - 5.25 GHz) and an axial ratio bandwidth (ARBW) of 2.0 GHz (2.2 - 4.2 GHz). Additionally, the antenna features a low profile, compact size, and broadside radiation with adequate gain. The geometry has been fabricated and reasonable agreement is observed between the simulated and measured responses.
