Problems solved by technology

The antenna structure with resonance characteristics is called antenna antenna, and the antenna structure directly excited by high-frequency current is called active antenna, otherwise it is called passive antenna; in the existing antenna, the antenna is adjusted according to the needs of actual use During design, in order to make the resonant frequency point of the antenna meet the setting requirements, the input impedance of the antenna needs to be adjusted. The adjusted antenna and the ordinary antenna still cannot meet the requirements of the current communication standard. The current communication standard is getting higher and higher. The requirements for antennas are getting higher and higher, and the gain, directivity, and front-to-back ratio of current antennas all need breakthroughs.

Abstract

The invention discloses a micro-strip double-layer antenna. The micro-strip double-layer antenna comprises a first PCB and a second PCB which are laminated together; a first micro-strip unit is arranged on the top surface of the first PCB; the first micro-strip unit comprises two micro-strip vibration sets which are same in shape and arranged symmetrically; a second micro-strip unit is arranged on the top surface of the second PCB; and when the first PCB and the second PCB are laminated, the second micro-strip unit is located at the top surface of the second PCB and the bottom surface of the first PCB. Excellent performances and gain of the antenna with a relatively good front-to-rear ratio are realized through excellent double-layer structure design as well as continuous testing and parameter adjustment. The antenna has the characteristics of low profile, broad band and high gain; the antenna 10dB has the impedance bandwidth of 28.4%; and the average gain of a single antenna is 8.2 dBi.

Description

technical field [0001] The invention relates to a microstrip double-layer antenna. Background technique [0002] An antenna is a device that converts high-frequency current into radio waves and transmits them into space, and at the same time collects space radio waves and generates high-frequency currents. The antenna can be regarded as a tuned circuit composed of capacitance and inductance; at certain frequency points, the capacitance and inductance of the tuned circuit will cancel each other out, and the circuit will show pure resistance. This phenomenon is called resonance, and the resonance phenomenon corresponds to The working frequency point is the resonant frequency point, and the energy at the resonant frequency point of the antenna has the strongest radiation characteristics. The antenna structure with resonance characteristics is called antenna antenna, and the antenna structure directly excited by high-frequency current is called active antenna, otherwise it is c...
