Horn-shaped antenna transmitting and emitting RF signals in different frequency ranges

Abstract

The invention provides a horn-shaped antenna transmitting and emitting RF signals in different frequency ranges, and aims at providing an emitter which is simple in structure, easy to process and capable of transmitting the RF signals in different frequency ranges simultaneously. The internal of an external dielectric layer (1) is connected with a metal layer (2), the external dielectric layer and the metal layer are coaxially fixed to the small end of a tapered horn of a metal horn body (4) in the vertical direction, and the external dielectric layer extends along the tapered surface of the metal horn body (4) via a small-end port of the tapered horn to form a horn dielectric layer (3); and the RF signals in different frequency ranges are transmitted to the small-end port of the tapered horn simultaneously via a dielectric body area of the external dielectric layer (1) and a conductor cavity of the metal layer (2) respectively, and are emitted via a dielectric area of the horn dielectric layer (3) and a conductor cavity of the metal horn body (4). According to the horn-shaped antenna, the problem that an RF signal waveguide structure capable of transmitting RF signals in the same frequency range cannot be structurally integrated with the antenna is solved.

Description

technical field [0001] The invention relates to a transmitting device capable of realizing simultaneous transmission and emission of multi-band radio frequency signals, and realizing structural integration of a transmission line and an antenna. Background technique [0002] The antennas used by the base station are divided into transmitting antennas and receiving antennas, and can be divided into omnidirectional and directional. Generally, there are three configuration methods: omnidirectional transmission and omnidirectional reception; omnidirectional transmission and directional reception; directional transmission, Receive orientation. It can be understood literally that each method is different. Sending omnidirectional is mainly responsible for all-round signal transmission; receiving omnidirectional is naturally the reception of azimuth signals; directional means only sending and receiving at a fixed angle. In general, base stations with fewer channels (such as located ...
