Abstract

The invention relates to and discloses a micro-strip antenna facing an optical and microwave coaxial detection application. The micro-strip antenna solves the problem that an existing micro-strip antenna can not achieve optical detection while emitting and receiving an electromagnetic wave. The micro-strip antenna comprises a transparent medium plate, a rasterization earth plate, a rasterization micro-strip patch, a rasterization micro-strip feeder line and a wave guide port, wherein the rasterization earth plate is fully spread on the lower surface of the transparent medium plate, the rasterization micro-strip patch is spread on the upper surface of the transparent medium plate, the center of the transparent medium plate and the center of the rasterization micro-strip patch coincide, the wave guide port is fixed on the side face of the transparent medium plate and is located at the middle position of the long edge of the transparent medium plate, the rasterization micro-strip feeder line is spread on the upper surface of the transparent medium plate and located between the wave guide port and the rasterization micro-strip patch, feed electricity is transmitted to the rasterization micro-strip feeder line and the rasterization earth plate through the wave guide port, and the rasterization micro-strip feeder line transmits the received feed electricity to the rasterization micro-strip patch. The micro-strip antenna is used for the coaxial optical detection of the optical and microwave detection.

Description

technical field [0001] The invention relates to a microstrip antenna for optical and microwave coaxial detection applications. Background technique [0002] The microstrip antenna is a new type of antenna that has been gradually developed in the past 30 years. It is based on a thin dielectric substrate, with a thin metal layer attached on one side as a ground plane, and a metal patch of a certain shape is made on the other side by photolithography and other methods. , use the microstrip line and the axis to feed the patch to form a microstrip antenna. The microstrip antenna was originally used as a common omnidirectional antenna on rockets and missiles. With the development of material science and technology, the practical microstrip antenna has been greatly developed, and it is now available in a wide frequency band from about 100MHz to 50GHz. received a large number of applications. The emergence of the microstrip antenna is an important achievement in the application of...
