Abstract

The invention discloses the technical field of communication and particularly relates to a unipolar oscillator antenna provided with a frequency-increasing gap and an isolating rod. The unipolar dipole antenna comprises a reflecting plate and a plurality of oscillator arranged on the reflecting plate, wherein each oscillator comprises two radiating elements which are connected by a feeder line and are symmetric from top to bottom; each radiating element comprises two oscillator chips which are arranged in bilateral symmetry; each oscillator chip comprises a first side wall, a first inclined arm and a second inclined arm and also comprises a second side wall; the first inclined arm extends obliquely and downwards from the top end of the first side wall to the direction of the other oscillator; the second inclined arm extends obliquely and downwards from the bottom end of the first side wall to the direction of the other oscillator; the second side wall is connected with the free end of the second inclined wall and is parallel to the first side wall. By excellent structure design, the front-to-back ratio of the lowest frequency point of single radiating element is larger than 30dB, and the front-to-back ratio in a frequency band is averagely larger than 32dB; and the average gain in the frequency band is larger than 9.8dBi.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a monopolar dipole antenna provided with a frequency increasing notch and an isolation rod. 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 oscillato...

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
