Suspended microstrip antenna array for 60GHz millimeter wave communication and antenna thereof

Abstract

The invention provides a suspended microstrip antenna array for 60GHz millimeter wave communication and an antenna thereof. The antenna array comprises antenna units and a feed network. The antenna units are arranged in an upper and lower two-row mode; the number of the antenna elements is 2*(2n), and n is a positive integer; the feed network comprises impedance transformers, coplane duel-wires, coplane waveguides and power dividers connected with the coplane duel-wires and the coplane waveguides; each antenna element is connected with one impedance transformer; the impedance transformers of the uplink antenna elements of the antenna units and the impedance transformers of the downlink antenna elements are arranged oppositely; the coplane duel-wires are connected with the antenna units via the impedance transformers; one power divider is connected at the axial central position of each coplane duel-wire; and one end of the coplane duel-wire is connected with the power divider and the other end is provided with a feed port. The suspended microstrip antenna has the advantages that the bandwidth is wide, the radiation loss is small, and integration with a plane millimeter wave circuit is easy.

Problems solved by technology

At present, low-frequency spectrum resources are very crowded, and it is difficult to meet the needs of future 5G communications. Opening up new frequency bands has become an inevitable choice for 5G. However, millimeter waves have unique properties such as rich spectrum resources, good orientation, and strong anti-interference capabilities. , has received more and more attention. Among them, the antenna at the front end of the millimeter wave transceiver system is particularly important. The performance of the antenna such as gain, bandwidth, and efficiency directly determines the quality of the system.

Conventional microstrip antennas have a narrow frequency band, which cannot meet the requirements of the 60GHz frequency band in the millimeter wave band, and the feeder has strong radiation loss, resulting in low efficiency of the entire antenna array
