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

Abstract

The invention discloses a microstrip oscillator with a parasitic oscillator. The microstrip oscillator comprises a dielectric plate, a first microstrip radiation unit and a second microstrip radiationunit. The first microstrip radiation unit and the second microstrip radiation unit are same in shape and are set on the front face of the dielectric plate in a left and right symmetric mode. Each ofthe first microstrip radiation unit and the second microstrip radiation unit comprises two opening and closing radiation strips which are symmetrical up and down and are same in shape. Each opening and closing radiation strip comprises a trapezoidal radiation strip. A short bottom edge of the radiation strip stretches upwards to form a first rectangular radiation strip. Left and right bevel edgesof the radiation strip stretch along directions vertical to the corresponding bevel edges to form a second rectangular radiation strip and a third rectangular radiation strip. An antenna has a good standing-wave ratio in a frequency range of 2GHz to 20GHz. The ultra wideband performance of the antenna is realized.

Description

technical field [0001] The invention relates to a microstrip vibrator provided with a parasitic vibrator. 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 the antenna structure directly excited by high-frequency current is called active ...
