Title:
LIGHTWEIGHT AND SMALL-SCALE MEASURING ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/019027
Kind Code:
A1
Abstract:
Disclosed is a lightweight and small-scale measuring antenna device, comprising a first signal-receiving unit, a second signal-receiving unit, a circuit board and a tuning unit, wherein the first signal-receiving unit comprises a substrate and a microstrip patch layer; the second signal-receiving unit comprises a metal member and a grounding member; the metal member is connected to the circuit board via the grounding member, the substrate is arranged on the metal member, and the microstrip patch layer is arranged on the substrate and shares an air radiation dielectric layer with the metal member; the tuning unit comprises a fixed plate, first tuning sawteeth, several second tuning sawteeth and several multipath inhibiting tuning sawteeth; and the fixed plate is arranged on the circuit board, the first tuning sawteeth are uniformly arranged on the metal member, and the second tuning sawteeth correspond to the first tuning sawteeth on a one-to-one basis. In the present invention, the first tuning sawteeth are arranged to correspond to the second tuning sawteeth on a one-to-one basis, so that as many of the first tuning sawteeth and second tuning sawteeth as possible are arranged within a limited area so as to better improve performance parameters such as an axial ratio bandwidth, a beam bandwidth and a low-elevation radiation gain while also achieving a small-scale structure; and the peripheral multipath inhibiting unit sawteeth can effectively inhibit the multipath effect of an antenna device, thus ensuring more accurate signal quality.
