Bipolar oscillator with frequency-increasing notches and isolating parts

Abstract

The invention discloses a bipolar oscillator with frequency-increasing notches and isolating parts. The bipolar oscillator comprises two vertically symmetrical radiating elements connected through a feeder line and two bilaterally symmetrical radiating elements connected through a feeder line. Each radiating element comprises two bilaterally symmetrical oscillator pieces. Each oscillator piece comprises a first side wall, a first oblique arm, a second oblique arm and a second side wall, wherein the top end of the first side wall extends downwards obliquely in the direction of the other corresponding oscillator piece to form the first oblique arm, the bottom end of the first side wall extends downwards obliquely in the direction of the other corresponding oscillator piece to form the second oblique arm, the second side wall is connected with the free end of the second oblique arm and is parallel with the first side wall, and the top end of the second side wall extends upwards obliquely in the direction of the first side wall to form a third oblique wall. A coupling bridge is connected between the second side walls of every two corresponding oscillator pieces. A feed arm is connected between the two radiating elements. Through the excellent structural design, excellent front-to-rear ratio characteristics are achieved, and the average in-band front-to-rear ratio is larger than 32 dB; the average in-band gain is larger than 9.8 bBi.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a bipolar vibrator provided with a frequency-increasing notch and an isolation part. 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 oscillator, and ...

AI Technical Summary

Problems solved by technology

The antenna structure with resonance characteristics is called antenna oscillator, and the antenna structure directly excited by high-frequency current is called active oscillator, otherwise it is called passive oscillator; in the existing oscillator, 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 vibrator and ordinary vibrator still cannot meet the requirements of the current communication standard. The current communication standard is getting higher and higher. The requirements of the vibrator are getting higher and higher, and the gain, directionality, and front-to-back ratio of the current vibrator all need breakthroughs
