High-gain steep filtering fusion duplex integrated antenna

Abstract

The embodiment of the invention provides a high-gain steep filtering fusion duplex integrated antenna. The high-gain steep filtering fusion duplex integrated antenna comprises a first dielectric plate, a second dielectric plate, a radiation patch, a feed network layer and a grounding patch, the radiation patch is provided with a long-strip-shaped first gap, the radiation patch is attached to one plate surface of the first dielectric plate, the plate surface of the second dielectric plate is parallel to the plate surface of the first dielectric plate, and the second dielectric plate is not in contact with the first dielectric plate; and the feed network layer comprises a first wiring port, a second wiring port, a first resonator and a second resonator, the feed network layer is attached tothe first plate surface of the second dielectric plate, the grounding patch is attached to the second plate surface of the second dielectric plate, and the grounding patch is provided with a long-strip-shaped second gap and a long-strip-shaped third gap. According to the high-gain steep filtering fusion duplex integrated antenna provided by the embodiment of the invention, multifunctional design can be realized under the condition that the complexity of a circuit structure is not increased only by pasting the patches and the feed network layers on the two dielectric plates, and the structure is simpler.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a high-gain steep filtering fusion duplex integrated antenna. Background technique [0002] With the rapid development of wireless communication technology, various wireless communication devices appear, wherein the antenna in the wireless communication device is a key component for realizing wireless communication. The duplex integrated antenna is widely used in various wireless communication devices because it can receive and send signals at the same time and has high communication efficiency. In practical applications, since wireless communication devices usually have a frequency range of their supported signals, the duplex integrated antenna usually also has a filtering function. [0003] In the prior art, usually two different monopole antennas provided with filtering components are placed together to form a duplex integrated antenna with a filtering function...
