A Yagi Filtering Antenna Based on Two Dipoles Array for 5G

A Yagi filtering antenna based on two dipoles array for 5G (5th generation wireless communication systems) is presented in this paper. The proposed antenna consists of two-layer substrate. The top layer have two dipoles array, a director and a reflector. And the bottom layer is a stub-loaded resonator (SLR), which is fed by SMA. The signal can be coupled to the two dipoles array. This antenna is also a low-profile structure with a height of 0.06 λ
₀
. The simulated -10 dB impedance bandwidth is 11% (3.29-3.67GHz). The peak gain in the bandwidth can reach 6.5 dBi.
