Abstract

A novel wideband CPW-fed elliptical slot antenna is proposed for ultra-wideband (UWB) applications. The design of the antenna includes a wide elliptical slot cut in the ground plane and an L-shaped radiator fed via a coplanar waveguide (CPW) line. By introducing a wide elliptical slot, the antenna achieves a broad impedance bandwidth. Additionally, the circularly polarized (CP) bandwidth is significantly enhanced by the introduction of a L-shaped radiator. For this antenna, the simulated impedance bandwidth reaches 99.8% (4.01GHz – 12GHz) and the simulated CP bandwidth is 91.9% (3.19GHz – 8.31GHz). The antenna, measuring 42mm × 42mm × 1mm, achieves a peak gain of 5.1dBic on the overlapping bandwidth (|S11| < -10dB, AR < 3dB).
