Problems solved by technology

[0005] However, if figure 1 As shown, the patch with the right quadrangular radiation pattern will spread the sensing area to the outside of the vehicle, so there is a problem of false sensing of the movement outside the vehicle (refer to figure 1 false sensing area)
[0006] However, when the output power (Power) is reduced in order to prevent false sensing of the movement outside the vehicle, there will be a shadow area where the movement in the vehicle interior cannot be sensed, and the problem of intrusion detection in the vehicle interior cannot be performed normally.

Abstract

The invention provides a patch antenna capable of being operated in an elliptical radiation mode, which is characterized by comprising a metal sheet capable of being operated in the elliptical radiation mode, a dielectric layer at the lower part of the metal sheet, and a power supply line connected with the metal sheet via a channel and used for transmitting message-reading signals to the metal sheet or receiving message-writing signals from the metal sheet.

Description

technical field [0001] The present invention relates to a patch antenna, and more particularly to a patch antenna with an elliptical radiation pattern applicable to indoor monitoring of vehicles. Background technique [0002] Generally, the vehicle intrusion sensing system senses the intrusion of the vehicle by using a patch antenna. [0003] Generally, the radiation pattern of the patch antenna is close to a circular shape, and the sensing area is also close to a circle. [0004] Therefore, in the vehicle intrusion sensing system, the interference effect of two or more patch antennas is used in order to apply the sensing area of ​​the patch antenna to a vehicle that is close to a rectangular shape. [0005] However, if figure 1 As shown, the patch with the right quadrangular radiation pattern will spread the sensing area to the outside of the vehicle, so there is a problem of false sensing of the movement outside the vehicle (refer to figure 1 false sensing area). [00...
