Abstract

Abstract: A wideband magneto‐electric dipole antenna with a claw‐shaped reflector is presented for future 5G communication systems. A pair of E‐shaped radiating patches is used to form an electric dipole, while two folded patches, which are shorted to the ground, are used as the magneto dipole. Four inverted‐L parasitic branches are introduced on the four corners of the ground, producing new resonant points. The four parasitic branches along with the ground plane form a claw‐shaped reflector for the antenna to obtain stable directional radiation patterns. This antenna is fed by a modified feeding structure to improve the matching of the working band. The measured results show that the reflection coefficient is less than ‐10 dB in a relative bandwidth of 103.6% (1.18‐3.72 GHz). The average gain in the working band is around 7.6 dBi. As a result, the proposed antenna can be a favorable candidate for future 5G communication systems.
