Microwave induction antenna module

Abstract

A microwave sensing antenna module comprising a substrate (3), a wave detecting mixer (35), and an oscillator (32). The substrate (3) is provided with a first lateral surface (3a). The first lateral surface (3a) is provided with a first area. The oscillator (32) is provided with an oscillator circuit structure (320) and a radiofrequency transistor (321) arranged thereon within the first area. The wave detecting mixer (35) is arranged on the first lateral surface (3a) and is provided with a wave detecting mixer circuit structure (350) and at least one wave detecting component arranged thereon. The oscillator circuit structure (320) comprises multiple structural segments (S1-S4). The structural segments (S1-S4) each comprise a curved part (C1-C4). Some of the structural segments (S1-S4) of the oscillator circuit structure (320) are connected to each other and some of the curved parts (C1-C4) are curved in the direction of the first area to be in proximity with or retracted from each other, thus greatly reducing the area to be occupied by the circuit layout. The microwave sensing antenna module is capable of reducing the overall size while ensuring effective microwave sensing.

Description

technical field [0001] The invention relates to a microwave induction antenna module, in particular to a microwave induction antenna module applied to an illuminating device. Background technique [0002] Ordinary lighting devices or lamps use traditional incandescent bulbs, lamp tubes or energy-saving bulbs as light-emitting elements to provide lighting, and most of the conventional control methods are to artificially control the flickering of these light-emitting elements. With the advancement of technology, the design of light-emitting diodes (LEDs) as light-emitting elements is becoming more and more widespread, and brings higher lighting effects. In addition, currently, the lighting device or lamp designed by using the motion sensing technology to control the flickering of the light-emitting element can more effectively achieve the purpose of saving energy. [0003] The so-called motion sensing technology is to install a sensor in the lighting device or lamp, which can...
