Problems solved by technology

[0002] In a wireless communication system, antennas, filters and duplexers are essential, but in the design of traditional wireless communication systems, antennas, filters and duplexers are integrated and connected by a 50-ohm transmission line. The design of the above antenna , on the one hand, it causes the size of the whole system to be large, on the other hand, it also reduces the efficiency and causes more transmission loss

Abstract

The invention discloses a novel dual-port feed four-frequency-band filtering duplex antenna. The antenna comprises: a radiation layer which is a metal patch provided with a U-shaped groove; a first dielectric substrate, wherein the upper surface of the first dielectric substrate is a radiation layer; a metal floor, wherein a gap is formed in the metal floor; and a second dielectric substrate, wherein the metal floor is arranged on the upper surface of the second dielectric substrate, a filtering feed network is arranged on the lower surface of the second dielectric substrate, and an air gap isarranged between the first dielectric substrate and the second dielectric substrate. According to the technical scheme provided by the invention, matching circuits among three elements in the traditional design are effectively reduced; the complexity of the antenna system is reduced, so that the size of the antenna system can be further reduced, and the structure becomes more compact; and meanwhile, the transmission loss among the filter, the duplexer and the antenna is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a novel double-port feeding four-band filtering duplex antenna. Background technique [0002] In a wireless communication system, antennas, filters and duplexers are essential, but in the design of traditional wireless communication systems, antennas, filters and duplexers are integrated and connected by a 50-ohm transmission line. The design of the above antenna , On the one hand, it causes the size of the whole system to be large, on the other hand, it also reduces the efficiency and causes more transmission loss. Contents of the invention [0003] The purpose of the present invention is to provide a novel dual-port feeding four-band filtering duplex antenna, which has simple structure, high efficiency, low cost and wide bandwidth, and is very suitable for satellite positioning systems. [0004] For realizing above-mentioned purpose of the inventio...
