A High Gain Steep Filter Fusion Duplex Integrated Antenna

Abstract

An embodiment of the present invention provides a high-gain steep filter fusion duplex integrated antenna, including a first dielectric board, a second dielectric board, a radiation patch, a feed network layer and a ground patch; In the first gap, the radiation patch is pasted on one surface of the first dielectric board, the board surface of the second dielectric board is parallel to the board surface of the first dielectric board, and the second dielectric board is not in contact with the first dielectric board; The feed network layer includes a first connection port, a second connection port, a first resonator, and a second resonator. The feed network layer is pasted on the first board surface of the second dielectric board, and the ground patch is pasted on the first board surface of the second dielectric board. On the second surface of the second dielectric board, the ground patch is provided with elongated second slits and third slits. The high-gain steep filter fusion duplex integrated antenna provided by the embodiment of the present invention can realize a multi-functional design without increasing the complexity of the circuit structure by pasting the patch and the feed network layer on two dielectric boards. 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...
