Compact Dual-Band Interleaved Multi-Beam Base Station Antenna

A compact dual-band dual-polarized interleaved six-beam base station antenna is proposed for LTE 1800/2600 carrier aggregation applications. It consists of two separate six beam subarrays: low band six beam array working at the frequency band of 1.7-2.4 GHz and high band six beam array working at the frequency band of 2.3-2.7 GHz. Through the asymmetrical non-uniform azimuth and elevation spacing arrangements, the azimuth beam coverage of the proposed dual-band 6/6-beam antenna at low band matches one of the antenna at high band.
