Abstract:

A broadband mmWave base station antenna with a double-layer symmetrical patch structure is presented in the article. The base station antenna consists of three-layer dielectric substrate, two pairs of patches, a microstrip line and four rectangular parasitic patches. The bandwidth of the antenna is increased by adding rectangular metal through holes on the dielectric substrate and slotting on the double-layer patch. Adding parasitic structures on the feed patch improves the impedance matching performance of the antenna. Simulation results show that the proposed antenna can achieve a -10 dB impedance bandwidth of 46.5% and a stable radiation pattern in the 24.04-38.64 GHz frequency band, and its in-band gain can reach 7.2±0.1 dBi. The proposed antenna has an ultra-wide impedance bandwidth and good gain effect, so it is promising as an alternative antenna for future 5G communication system applications.
