Title:
MICROWAVE DETECTOR HAVING GROUNDING POINT AND MANUFACTURING METHOD FOR MICROWAVE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2021/035866
Kind Code:
A1
Abstract:
Disclosed are a microwave detector having a grounding point and a manufacturing method for the microwave detector. The microwave detector comprises a radiating slot, a reference ground, and a radiation source, and the radiating slot is provided between the radiation source and the reference ground. The radiation source is further provided with a central grounding point, at least one left-side grounding point, and at least one right-side grounding point; the central grounding point allows a zero-potential point of the radiation source to be grounded, the left-side grounding point allows a position of the radiation source on the left side of the zero-potential point to be grounded, and correspondingly, the right-side grounding point allows a position of the radiation source on the right side of the zero-potential point to be grounded, so that the radiation energy of the microwave detector tends to be uniformly distributed, the loss of the microwave detector is reduced, the receiving and transmitting efficiency of the microwave detector is improved, and the gain of the microwave detector can be enhanced.
