AI Technical Summary

Technical Problem

The existing slot antennas are large in size and heavy in weight, making it difficult to meet the structural size and weight requirements integrated in the entire system, and are particularly obvious in the use of the meter wave frequency band.

Method used

An antenna including rabbit ear plate-shaped blades and polarized grids was designed. The blade boundary is surrounded by multiple arc arms, connected by protective blocks, combined with hollow structure and metal floor, and the current transmission circuit is extended and The reduction in reflection further reduces the blade height and weight.

Benefits of technology

The antenna is miniaturized and lightweight design is realized, which meets the structural size and weight requirements of the entire system, and improves the stability and reliability of the antenna, which can reduce the volume by 30% within 2 to 3 frequency ratio bandwidths, and Maintain the same electrical performance.

Abstract

The present invention provides an antenna and a polarization grid mechanism. The antenna includes: a pair of blades, a protective block and a polarization grid mechanism. The blades are rabbit-ear-shaped plate structures. The boundaries of the blades are surrounded by a plurality of arc arms. A pair of blades are connected by the protective block, and a pair of the blades are installed in the polarization grid mechanism. The blades are rabbit-ear-shaped plate structures and the blades are rabbit-ear-shaped plate structures to achieve broadband. The arc arms are used to increase the length of the current transmission loop while reducing reflection. The structural design of the polarization grid further reduces the height of the blades, effectively reducing the size of the blades, and realizing the miniaturization design of the antenna. The protective block is used to ensure the insulation between the pair of blades and prevent short circuits between the pair of blades. It is simple to assemble, small in size, and light in weight, and can meet the structural size and weight requirements of the full system integration.
