- Abstract
- A simple-structured single-fed dual-slot broadband antenna with circularly polarized waves is presented. Two semicircular slots etched in the ground plane were used as the radiators. The slots were proximity-coupled to a 50 Omega microstrip feedline printed on the other side of the substrate. The fabricated antenna with an overall size of 101 x 64 x 1.52 mm(3) yielded a very wide -10 dB impedance bandwidth of 86.9% (3.63-9.21 GHz) and a 3 dB axial-ratio bandwidth of 74.3% (4.18-9.12 GHz). The measured antenna peak gain in the broadside direction over the axial-ratio bandwidth ranged from 3.9 to 7.3 dB. Good agreement between the simulated and measured results validates the proposed antenna.
