Description

technical field [0001] The invention relates to the field of communication technology, in particular to a unipolar vibrator provided with a rectangular via hole. 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 dire...

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
