Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] In the present invention, unless stated otherwise, the used orientation words such as "inner and outer" generally refer to the inner and outer sides of the corresponding object outline. The used orientation words such as "up, down, left, right, front and back" usually refer to the up, down, left, right and front and back of the corresponding object.

[0025] Such as figure 1 As shown, the broadband dual circular polarization low rear lobe integrated transceiver antenna provided by the present invention includes: a metal choke coil 1, the metal choke coil 1 is a multi-layer metal concentric circular cavity structure with a closed bottom surface; a radio f...

Abstract

The invention discloses an antenna, which comprises a metal choke ring, a radio-frequency connector, a feed network and a radiation patch, wherein the metal choke ring is in a multi-layer metal concentric circular cavity structure with a closed bottom surface; the radio-frequency connector is arranged at the bottom surface of an inner cavity of the metal choke ring; and the feed network and the radiation patch are fixed at the top end of the inner cavity from bottom to top. The invention further discloses a platform telemetering system with the antenna. The antenna is excellent in performance and simple and reliable in structure and technology, has relatively high gain bandwidth and isolation and can simultaneously achieve left-hand circularly polarized radiation and right-hand circularly polarized radiation; the radiation pattern back lobe is relatively small; the axial ratio performance is excellent; and meanwhile, the performance of the antenna is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to the technical field of antennas with wide frequency band, dual circular polarization, low rear lobe, and shared transmission and reception, and is suitable for telemetry systems with miniaturized, light weight, and complex structure platforms. Background technique [0002] Existing low-lobe antennas generally use metamaterial-based structural models, such as the patent "antenna reflector and low-lobe antenna" (application number: CN201320717530.9), and the patent "providing a reduced back-lobe Fresnel area Microstrip antenna" (application number: CN201210425430.9), the metamaterial structure of this type of antenna leads to low radiation efficiency of the antenna, and the formed high-resistance bandwidth is narrow, which is not suitable for the requirement of reducing the back lobe of the broadband antenna; at the same time, The high-resistance structure formed in the form of a ...
