Abstract
This paper presents planar modified circular slot antenna with asymmetric Y-shaped feeding technique. The CPW asymmetric Y-shaped feeding structure is electromagnetically coupled to the modified circular shaped radiating patch. The proposed antenna is made circularly polarized by innovative Y-shaped asymmetric arm feeding structure. The antenna covers the impedance bandwidth of 2.04GHz–4.38GHz with center frequency 2.49 GHz. The impedance bandwidth of the proposed antenna is improved and enhanced compared with the reference antenna. The circular polarization purity at resonant frequency is achieved by the proposed feeding technique. The fractional bandwidth achieved is of 72.89%, while the axial ratio bandwidth is 73.33MHz. The radiation patterns are bipolar in nature in E & H plane. The peak gain 5.13dB and the VSWR bandwidth 2.4GHz (2.02GHz–4.4GHz)of the proposed antenna finds the wireless application, such as 802.11b/2.5GHz and 802.16e/3.5GHz.
