The invention relates to the technical field of base station communication, and discloses a small-caliber filtering oscillator used for a multi-frequency base station antenna, the small-caliber filtering oscillator comprises a radiation surface, a first balun, a second balun and a substrate, the radiation surface is formed by processing a double-sided copper-clad dielectric plate, the dielectric plate is a hard plate, enough structural strength is maintained, and the radiation surface is made of metal. The line width of the main body microstrip line on the radiation surface is less than 1mm, so that the physical interference to other system antennas can be effectively reduced. According to the small-caliber filtering oscillator for the multi-frequency base station antenna, the width of the antenna can be effectively reduced while the physical interference is reduced, so that the antenna gain is effectively improved on the premise of meeting the windward area requirement of an iron tower building station. For example, after the small-caliber filtering low-frequency (690-960MHz) oscillator is applied, the width of a base station antenna with eight high-frequency (1690-2690MHz) channels and four low-frequency (690-960MHz) channels coplanar can be reduced from about 600mm to within 470mm, and the actual application of a frequency system fused antenna array is comprehensively improved.
Description
technical field [0001] The invention relates to the technical field of base station communication equipment, in particular to a small-diameter filter oscillator used for multi-frequency base station antennas. Background technique [0002] On the base station side, the multi-frequency base station antenna has a wider antenna width due to the integration of multiple frequency band antenna arrays, resulting in a generally larger windward area and a higher drag coefficient. Since iron towers and poles have strict requirements on the drag coefficient, Therefore, the base station antenna needs to solve the following problems, compact design, to achieve a large reduction in width, so as to reduce the front and wind resistance coefficient of the entire base station antenna, as well as the volume and weight of the antenna, specifically, this includes the miniaturization of the antenna unit itself design and design for decoupling / improved isolation between individual antenna elements....
