Abstract
The invention provides a compact decoupling MIMO terminal antenna for 5G mobile communication. The antenna mainly comprises a main substrate, two small substrates and eight antenna units; the two small substrates are vertically placed on the two sides of the main substrate, each small substrate is provided with four antenna units and is divided into two antenna pairs, the antenna units in each antenna pair are in mirror symmetry, a lumped inductance element is loaded between the antenna units in each antenna pair, and an LC parallel band-stop filter circuit is formed by capacitive coupling between the band-stop filter circuit and the antenna unit; and the antenna unit is composed of a first IFA antenna and a second IFA antenna, and each antenna unit is connected to the microstrip line feed from the back of the substrate through a via hole by a connector. According to the invention, the miniaturization design of the antenna structure is realized, and the application requirement of covering a 5G mobile communication frequency band and the miniaturization design trend of a terminal antenna can be met.
Description
technical field [0001] The present application relates to the field of antenna technology, in particular to a compact decoupled MIMO terminal antenna for 5G mobile communications. Background technique [0002] With the rapid development of fifth-generation mobile communication (5G) technology, it provides higher throughput and shorter latency for wireless communication systems. As one of the key technologies of 5G systems, multiple-input multiple-output (MIMO) can increase channel capacity without occupying additional spectrum or power resources. In 5G smartphones, 4 to 8 MIMO antennas operating below 6 GHz are used to simultaneously transmit multiple data streams for a single user. However, due to the limited space allocation and complex environment of modern smart mobile terminals, the design of MIMO antennas for 5G mobile communication mainly faces two major challenges. First, effective decoupling techniques are used to reduce the space occupied by multi-antenna systems...
