Meandered-line inductor feed and partial ground plane are used for generation of orthogonal modes, hence circular polarization (CP) in DRA. By controlling the length of meandered-line inductor, three different CP DRA have been designed for different wireless applications such as Wi-MAX and WLAN/ISM 2400 band. Distribution of electric field inside rectangular DRA shows that all three antenna having TE11δ mode. Finally, a lower frequency band application at 2.4 GHz (ISM) called here as Proposed Antenna, has been considered for fabrication. This designed antenna shows measured −10 dB input impedance bandwidth of 20.67% and 3-dB axial ratio bandwidth of 27.95% in broadside direction. All these three CP antennas (Antenna-1 to Proposed Antenna) are showing stable gain and right hand circular polarization in broadside direction.
