Abstract

This paper proposes a magneto-electric dipole antenna with broadband, good directivity, and high gain. By changing the shape of the radiating patch and loading the T-slot to improve the impedance matching ability of the antenna, the bandwidth is effectively expanded. Low cross-polarization and high gain are achieved by using a square metal reflective cavity and a hollow metal cylinder loaded on top of the antenna. Test results show a relative impedance bandwidth (|S₁₁|<-10 dB) of 94.40% (1.32 GHz-3.68 GHz) with a maximum gain of 10.7 dBi. The antenna has excellent performance and has applications in wireless communication systems.
