Micro-strip combiner and installation structure thereof

Abstract

The present invention discloses a micro-strip combiner. The micro-strip combiner comprises a high-frequency branch having a frequency range of 2300MHz-2690MHz and a low-frequency branch having a frequency range of 1710MHz-2170MHz which are arranged on a micro-strip board, and the high-frequency branch and the low-frequency branch combine one combiner output port. The cost is reduced while the electrical indexes are ensured, a certain technology difficulty is broke through, and the fine optimization is performed at the aspects of dimension control and installation technology. Besides, a connection port is a welding form, and compared to an N-type screw thread interface used by a general cavity combiner, the micro-strip combiner and the installation structure thereof are better in intermodulation stability.

Description

technical field [0001] The invention relates to the technical field of antenna equipment, in particular to a microstrip combiner inside a dual-frequency or multi-frequency antenna. Background technique [0002] With the rapid development of the integration of communication systems, the requirements for the size of the antenna are getting smaller and smaller, and more and more frequency bands are integrated. Signals of different frequency bands generally require independent interfaces, but due to equipment, technology and demand reasons, sometimes the signals of two frequency bands must be combined for input or output, which requires a dual-frequency combiner to achieve. At present, there are two types of dual frequency combiners on the market: cavity and microstrip board. Although the cavity combiner with better optimization results has stable performance and extremely small insertion loss, the materials used are all metal, and The volume is bulky and the cost is high. The...

Problems solved by technology

At present, there are two types of dual frequency combiners on the market: cavity and microstrip board. Although the cavity combiner with better optimization results has stable performance and extremely small insertion loss, the materials used are all metal, and Bulky and expensive

The biggest advantage of the microstrip board is that it is small in size, light in weight, and very low in cost, but the disadvantage is that the bandwidth is narrow, and due to technical limitations, most of the occasions cannot meet the requirements.
