Problems solved by technology

Furthermore, especially in the case of current electronic devices that require light, thin, and small antennas, the area of ​​the circuit fed into the network may be larger than the antenna array, making it difficult to reduce the overall size of the antenna array module, making it difficult to reduce the overall size of the antenna array module. Substantial increase in the manufacturing cost of antenna products

Abstract

The invention discloses an antenna with eight modes. The antenna comprises a ground plane, an omnidirectional antenna, a first parasitic element, a second parasitic element, a third parasitic elementand a fourth parasitic element. The first parasitic element, the second parasitic element, the third parasitic element and the fourth parasitic element are symmetrically erected around the omnidirectional antenna with the omnidirectional antenna as the center. The first parasitic element is connected with the ground plane through a first capacitor and is conducted with the ground plane through a conducted first diode so as to shorten a grounding path. The second parasitic element is connected with the ground plane through the second capacitor and is conducted with the ground plane through theconducted second diode so as to shorten the grounding path. The third parasitic element is connected with the ground plane through a third capacitor and is conducted with the ground plane through a conducted third diode so as to shorten a grounding path. The fourth parasitic element is connected with the ground plane through a fourth capacitor and is conducted with the ground plane through a conducted fourth diode so as to shorten a grounding path. The conduction states of the diodes are used for controlling the generation of eight modes.

Description

technical field [0001] The invention relates to an antenna, especially an antenna with eight modes. Background technique [0002] The radiation pattern of the antenna varies according to the basic working principle of the antenna. Various radiation patterns have different applications. For example, the omnidirectional radiation pattern is suitable for the terminal device so that the terminal device can receive wireless signals from all directions. Signal. For another example, base station antennas, such as wireless access point antennas, may need to be able to generate radiation patterns in specific directions, so as to perform wireless communication with terminal devices located in various specific locations. [0003] Generally speaking, although an array antenna can be used to control a specific radiation pattern, the control circuit of the array antenna (including switches, phase control, and feeding network, etc.) introduces more problems of transmission loss.
