Unipolar high-gain microstrip oscillator

Abstract

The invention discloses a unipolar high-gain microstrip oscillator. The oscillator comprises two oscillator sheets arranged centrosymmetrically. Each oscillator sheet is provided with a plurality of hollow isolating slots parallelly, and each isolating slot is provided with a plurality of loading holes in two sides. Through such a reasonable structural design, distributed load technology is used on a radiation unit. Through comprehensive optimization of a series of technologies, an antenna is further miniaturized, thereby satisfying the requirements of a communication system in the prior art. With the above structure, the oscillator realizes antenna radiation directional diagram control characterized by directional radiation with a high gain. Thus the oscillator is characterized by high symmetry, high integrated level, miniaturization, good radiation features, high gain, low costs and easy integration.

Description

technical field [0001] The invention relates to the field of oscillators, in particular to a unipolar high-gain microstrip oscillator. Background technique [0002] Nowadays, with the wide application of satellite communication systems, research on receiving antennas for satellite communication systems emerges in an endless stream, such as monopole, dipole, helical, four-arm helical and microstrip antenna structures, all of which can be used in satellite communication systems. Among various antennas; the traditional microstrip antenna has been used in mobile communications due to its advantages of low profile, small size, light weight, conformability, easy integration, flexible feeding methods, and easy access to linear polarization and circular polarization. Satellite communications, missile telemetry, Doppler radar and many other fields have been widely used, but the limited gain has always been the defect of microstrip antennas; microstrip antennas are a new type of anten...

[0002] Nowadays, with the wide application of satellite communication systems, research on receiving antennas for satellite communication systems emerges in an endless stream, such as monopole, dipole, helical, four-arm helical and microstrip antenna structures, all of which can be used in satellite communication systems. Among various antennas; the traditional microstrip antenna has been used in mobile communications due to its advantages of low profile, small size, light weight, conformability, easy integration, flexible feeding methods, and easy access to linear polarization and circular polarization. Satellite communications, missile telemetry, Doppler radar and many other fields have been widely used, but the limited gain has always been the defect of microstrip antennas; microstrip antennas are a new type of antennas that have been gradually developed in the past 30 years It has been widely used due to its advantages, but it also has disadvantages such as small gain, poor directivity, existence of surface waves, and insufficient bandwidth.
