Wideband Dipole Antenna and Array Based on Liquid Crystal Polymer for 5G Applications
In this paper, a wideband end fire dipole antenna and array based on liquid crystal polymer (LCP) is proposed for fifth generation (5G) applications. Meandered or bent arm is adopted in the dipole antenna design to reduce its size. Meanwhile, a director is added in front of the dipole, which not only improves the gain, but also generates a new resonance to expand the bandwidth. The simulated results show a wide bandwidth from 22.5 GHz to 30.2GHz with end fire radiation and good beam steering characteristic. Two antenna prototypes, including an antenna element and an array are fabricated and the experimental results demonstrate good agreement with the simulated ones.
