A broadband printed slot antenna with wide E-plane beamwidth

摘要

A novel coplanar waveguide fed printed rectangular slot antenna is proposed in this paper, which consists of a substrate layer of the CPW-fed rectangular slot antenna, a composite cavity, and a SMA connector with the vertical transition structure. The simulated results indicate that the antenna has the 10dB impedance bandwidth of 49%, the 3-dB beamwidth of exceeding 107° in E-plane, the gain of 6dBi, and with a compact size.
