Abstract

The invention discloses a wideband filtering slot antenna and wireless communication equipment. The antenna comprises a dielectric substrate, a microstrip feeder, a floor, two stepped impedance filterbranches and two parasitic patches, wherein the microstrip feeder and the two stepped impedance filter branches are all arranged on an upper surface of the dielectric substrate, the two stepped impedance filter branches are symmetric about the microstrip line and are respectively connected with two sides of the microstrip feeder, the floor is arranged on a lower surface of the dielectric substrate, a dumbbell-shaped gap is etched in the floor, the two parasitic patches are symmetrically arranged at two end groove gaps of the dumbbell-shaped gap, and the wireless communication equipment comprises the antenna. The wideband filtering slot antenna has filtering characteristics, is easy to process, is simple in structure, is low in cost and wide in frequency band and can be applied to wirelesscommunication systems of ISM, Wi-MAX and 5G within a range of 2.14-4.04GHz.

Description

technical field [0001] The invention relates to a filter antenna, in particular to a broadband filter slot antenna and wireless communication equipment, belonging to the technical field of wireless communication. Background technique [0002] With the rapid development of wireless communication technology, all kinds of electronic equipment are developing in the direction of broadband and multi-function, and the antenna, as a bridge and air interface of wireless communication technology, is bound to develop in this direction. The traditional antenna does not have filtering function, so the RF front-end usually needs to add a filter to meet the practical requirements, and the addition of the filter will not only increase the volume of the device, but also bring additional loss; so the filter antenna with filtering function has been developed . However, the general filter antenna has a narrow frequency band, which has caused the antenna to be unable to meet the wireless commun...
