Bending antenna array and layout method thereof

Abstract

The invention discloses a bent antenna array and a layout method thereof. The antenna array comprises a substrate and a plurality of same unit antennas arranged on the substrate, the plurality of unit antennas independently feed and include a central antenna and a row of peripheral antennas which are collinear with the center antenna and are symmetrically arranged on the two sides of the central antenna; the substrate is flexible and bent toward the back with the central antenna as the center, so that the peripheral antennas are symmetrically arranged on the two sides of the curved surface of the substrate. According to the invention, the directional diagram of the antenna array is adjusted by bending the substrate, the fabrication and application methods of the antenna array are simple, and the performance of the assembled unit antenna is not changed; each unit antenna is configured as independent feeding, and can be re-matched and integrated via a back-end circuit after feeding, so as to reduce the impedance matching difficulty and accuracy between the antennas. In addition, the number of the unit antennas can be increased or decreased according to the actual requirements to meet the communication needs, and the practicability is high.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a bent antenna array and an arrangement method thereof. Background technique [0002] As a component used to transmit or receive radio waves, the antenna plays a pivotal role in the wireless communication system and is an indispensable part of the wireless communication system. With the rapid development of high-frequency satellite communication systems, radar, wireless communication systems, especially the construction of global 3G and 4G networks, the requirements for antennas are getting higher and higher. On the one hand, it is necessary to make the antenna sensitive to weak signals, receive very weak signals far away, and transmit weak signals to long distances. At the same time, it is hoped that the coverage area of ​​the antenna will be large, and even 360° without dead angle. Just because of such demands, various antenna arrays have been proposed ...

AI Technical Summary

Problems solved by technology

The general single antenna has various styles, but its energy efficiency is always limited.

Either its gain is very small, and its transceiver capability is very limited; or its directivity is very narrow, and its radiation coverage is very small
