Power divider and Balun composite circuit network

Abstract

The invention relates to a power divider and Balun composite circuit network which comprises an upper dielectric substrate, a lower dielectric substrate, a film substrate and metal layers arranged on the three substrates. The metal layers comprise an upper halving power divider attached to the upper surface of the upper dielectric substrate, a lower halving power divider attached to the lower surface of the lower dielectric substrate and a center core wire attached to the upper surface of the film substrate. The upper dielectric substrate and the lower dielectric substrate are distributed in parallel. The upper halving power divider and the lower halving power divider are in mirror-image relation. The film substrate is clamped between the upper dielectric substrate and the lower dielectric substrate without any gaps in the middle. The center core wire is parallel to the upper halving power divider and the lower halving power divider and is placed between the upper halving power divider and the lower halving power divider, and the distance between the center core wire and the upper halving power divider and the distance between the center core wire and the lower halving power divider are equal. According to the network, the upper halving power divider, the lower halving power divider and the center core wire form a strip-shaped circuit mode, a formed Balun composite circuit is simple, the network has the advantages that achieving is easy, the isolation degree is large, and frequency bandwidth is relatively large.

Description

technical field [0001] The invention relates to a phased array scanning antenna, in particular to a composite circuit network of a power divider and a balun. Background technique [0002] In modern phased array scanning antennas, a multi-mode forming network is necessary. This multi-mode forming network is called a Butler (Butler) network, and its performance directly determines the scanning quality of the phased array antenna. The power divider and balun compound circuit network are the key components of the Butler network, and a complex Butler network is composed of multiple power dividers and balun compound circuit networks. The realization of the power divider and the balun composite circuit network is relatively difficult, the isolation between each input is not ideal, and the frequency band is also very narrow. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the present invention provides a simple and easy-to-implement, hi...
