Stereo type flat plate antenna

Abstract

The stereotype tabulate antenna includes a reflection unit, a first radiating element (RE), and a second RE. The reflection unit possesses a first reflection plane (RP), and a second RP. Being setup opposite to the first RP of the reflection unit, the first RE possesses a first radiation portion, and a first electrical connection portion. One end of the said first electrical connection portion is connected to the first radiation portion electrically, and the first radiation portion is parallel to the first RP approximately. Being setup opposite to the second RP of the reflection unit, the second RE possesses a second radiation portion, and a second electrical connection portion. The second radiation portion is parallel to the second RP approximately. One end of the second electrical connection portion is connected to the second radiation portion electrically, and the other end is connected to the other end of the first electrical connection portion.

Description

technical field [0001] The invention relates to an antenna, in particular to a three-dimensional planar antenna which can change the radiation pattern according to actual needs, has high power gain, low power loss and can reduce receiving noise. Background technique [0002] With the vigorous development of wireless transmission, various products and technologies applied to multi-frequency transmission are brought at the same time, so many new products will have the performance of wireless transmission, so as to meet the needs of consumers. The antenna is an important component used to transmit and receive electromagnetic wave energy in the wireless transmission system. If there is no antenna, the wireless transmission system will not be able to transmit and receive data. Therefore, the role of the antenna is an indispensable part for wireless transmission. [0003] In addition, choosing an appropriate antenna can not only help to match the appearance of the product and imp...

AI Technical Summary

Problems solved by technology

[0004] Current antennas can be roughly divided into two types: omnidirectional antennas and directional antennas. Among them, omnidirectional antennas have a wider angle of receiving and transmitting signals, but are also more likely to receive noise and noise when receiving signals; and The power gain of the directional antenna is higher, and compared with the omnidirectional antenna, the received noise and noise are smaller, but the angle of the transmitted signal is narrower

In addition, regardless of whether it is an omnidirectional antenna or a directional antenna, the radiation pattern is fixed after the antenna design is completed, and the user cannot change the radiation pattern according to actual needs to adapt to the environment in which the antenna is used.

[0005] It can be seen that the above-mentioned existing antenna obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems of antennas, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above-mentioned problems. This is obviously a problem. Issues that relevant industry players are eager to solve
