Abstract
A miniaturized antenna with a simple approach to generate CP over a wide frequency range is presented in this communication. The proposed design consists of an unsymmetrical slotted ground and two horizontal radiating elements that are attached to the feed-in the direction opposite to each other. The resulting ARBW attained with this design stage is 33.06% (3.66-5.11 GHz). To further enhance the axial ratio bandwidth (ARBW), modifications in the ground plane are made by adding two radiating parasitic elements in the vertical direction. The final proposed antenna features a compact geometry with a dimension of 28×28 mm2 and ARBW (AR≤ 3-dB) of 47.42% (3.7-6 GHz) within the -10dB impedance bandwidth (IBW) of 66.12% (3.27-6.5 GHz).
