Miniature microwave induction antenna

Abstract

The invention discloses a miniature microwave induction antenna, which comprises an antenna chip, and is characterized in that the surface of the antenna chip is provided with an oscillation module, an adjustment module, a signal amplification module, a filtering module, an input signal end, a GND end and an OUT end. A first capacitor, a second capacitor, a third capacitor and a fourth capacitor are four 104 capacitors, the four capacitors play a role in oscillating filtering of the whole antenna, the first resistor and the fifth capacitor are matched with each other to play a role in amplifying and biasing the microwave antenna, and by adjusting the high-frequency tube, the second resistor can amplify the power of the whole antenna, a high-frequency tube plays a role in amplifying a microwave antenna signal, and a sixth capacitor plays a role in filtering and amplifying the signal output of the microwave antenna, so that the interference of a relatively strong radio frequency signal in a working environment on the antenna is avoided, the misjudgment reaction of the induction antenna is prevented, the induction reliability of the antenna is improved, and the application range of the antenna is expanded.

Description

technical field [0001] The invention relates to the technical field of induction antennas, in particular to miniature microwave induction antennas. Background technique [0002] Antenna is a kind of transformer, which transforms the guided wave propagating on the transmission line into the electromagnetic wave propagating in the unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, antennas are also required for non-signal energy radiation. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna, and the same ant...

AI Technical Summary

Problems solved by technology

[0003] At present, when the common induction antennas on the market are used, when there is strong radio frequency signal interference in the working environment, the induction antenna will have a misjudgment reaction, which will reduce the reliability of the antenna’s induction, and the application range of the antenna has certain limitations. sex, which brings great inconvenience to users, so we propose a miniature microwave induction antenna
