Abstract

The invention discloses a miniaturized ultra-wideband low-frequency radiation unit, which is applied to a high-low frequency nested array. The low-frequency radiation unit is composed of four groups of monopole radiation electric arms with disconnected middle parts and sheet metal baluns with windows laminated up and down, and a coupling metal sheet is loaded between two adjacent monopole radiation electric arms; and a pair of the monopole radiation arms which are diagonal to each other have the same polarization direction, 75-ohm radio frequency cables with the same length are welded at a feed point, and the two 75-ohm cables in the same polarization direction are welded together through a feed groove and then are connected with a 50-ohm feed line for excitation. The miniaturized ultra-wideband low-frequency radiation unit has the advantages of the small size, the light weight, the ultra wide band, simple matching and low cost. The invention also provides a high and low frequency nested array.

Description

technical field [0001] The patent of the present invention relates to the field of base station antennas, in particular to a miniaturized ultra-broadband low-frequency radiation unit in a coaxial nested spatial multiplexing array and a high-low frequency nested array composed of the above-mentioned low-frequency radiation unit. Background technique [0002] The arrival of 5G puts forward higher requirements for the miniaturization and integration of base station antennas. As a relatively mature technology for reducing the size of base station antennas and improving integration, the coaxial nested spatial multiplexing array of high and low frequency radiating units has been widely used in the industry and has become the main method to solve the problems of miniaturization and integration. one. [0003] The coaxial nested spatial multiplexing array of high and low frequency radiation units is to install the high frequency radiation units at intervals on the support platform a...
