Abstract

The invention provides a double-frequency high-gain dielectric resonance array antenna. The antenna comprises a substrate, two microstrip feed networks and a dielectric resonant unit array composed of N dielectric resonant units, N >=1, the microstrip feed networks are arranged on the substrate, the N dielectric resonant units are arranged on the substrate in a coaxial or collinear arrangement manner, feed points of the dielectric resonant units are coupled to the output ends of the two microstrip feed networks, first feed slots are arranged in two side surfaces of each dielectric resonant unit, and a second feed slot is arranged in the bottom surface of each dielectric resonant unit. One microstrip feed network is provided with a group of coupling apertures close to the output end of a dielectric cube, the other microstrip feed network is provided with a group of coupling probes close to the output end of a dielectric cube, the coupling probes and the first feed slots form a coupling power, the coupling apertures are formed in the substrate and coupled with the second feed slots. The high-gain dielectric resonance array antenna is compact in structure, low in weight, low in loss, high in efficiency, low in cost, easy to assemble and suitable for batch production and includes fewer welding points, and can be used to provide effective or beneficial references for design and improvement of other broadband, multi-frequency, low-gain dielectric resonant units or array antennas.

Description

[0001] 【Technical field】 [0002] The invention relates to a mobile communication base station antenna device and technology, in particular to a dual-band high-gain dielectric resonant array antenna and its technology. [0003] 【Background technique】 [0004] The base station antenna is the air interface between the user terminal of the mobile communication system and the system network, and its impact on the performance of the entire communication system is even more critical and decisive. In the long-term technological evolution, the base station antenna has formed the current mainstream technical solution that uses the die-casting vibrator as the basic radiating unit, selects the coaxial cable or printed wire to construct the feed network, and uses the pull-rod phase shifter to realize the electric downtilt. In the 2G / 3G / 4G frequency band (698-960 / 1710-2700MHz), the size of the vibrator is usually on the order of 30mm-150mm, and the die-casting process can meet its precision...
