A Dual-polarized Electromagnetic Transparent Antenna for Dual-band Antenna Array

This paper proposes a novel electromagnetic transparent antenna for dual-band antenna array. The proposed antenna has good radiation characteristics in the low-band (LB) 820-960MHz (4G band) and it has slight interference with the radiation in the high-band (HB) 3.4-3.6GHz (5G band). The antenna is designed to suppress HB induce current by introducing ideal inductances. The simulation results show that the proposed antenna achieves high port isolation (>28dB) and VSWR<2 over the entire operating frequency band, and it is electromagnetic transparent to HB radiation. The electromagnetic transparent antenna can form a small-size dual-band antenna array which will be widely used in future wireless communication systems.
