Dual-polarization wide-stop-band filtering antenna and communication equipment

Abstract

The invention discloses a dual-polarization wide-stop-band filtering antenna and communication equipment, and the antenna comprises a dielectric substrate, a metal floor, a metal radiation paster, a metal feed arm, a metal square ring branch knot, a metal transverse branch knot, and a metal probe, the dielectric substrate is of a rectangular cavity structure, and the metal floor is disposed on thelower surface of the dielectric substrate. The metal radiation paster is arranged in the middle of the upper surface of the dielectric substrate, the metal transverse branch knot and the metal squarering branch knot are located in the rectangular cavity, located on the same layer and connected, the metal feed arm is located between the metal square ring branch knot and the metal radiation paster, and one end of the metal probe and a round hole formed in the metal floor form a coaxial feed structure. And the other end of the metal probe passes through the metal transverse branch knot and is connected with one end of the metal feed arm to form a dual-polarization differential feed structure, and the metal probe is connected with the metal transverse branch knot. The antenna is simple in structure, the size of the radio frequency front end can be greatly reduced, and extra insertion loss is avoided.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a dual-polarized wide-stop band filter antenna and communication equipment. Background technique [0002] With the advent of the 5G era, the development of massive multiple-input multiple-output antenna technology (MIMO) has become the key to 5G applications. In order to accommodate more RF transceiver channels in a limited space to cover broadband applications, the development of communication systems tends to be miniaturized, low power consumption, and multifunctional. Antennas and filters in the front end of radio frequency systems are essential passive components, and performance design is particularly important. The main function of the filter is to filter out noise and unnecessary clutter, etc., and the antenna is the terminal device for sending and receiving signals. Generally speaking, the antenna and filter work separately, which not only increases the system loss and reduces t...

Problems solved by technology

Such a design has a large loss and is difficult to miniaturize. Therefore, the filter antenna design of "integrated antenna in package" that can be applied to millimeter wave and higher frequency bands can be one of the methods to solve this problem.
