Description

technical field [0001] The invention relates to a bipolar vibrator provided with isolation bands. Background technique [0002] At present, micro-single antennas have become the mainstream of communication, especially miniaturized antennas. 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 resonant characteristics is called an...

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 resonant characteristics is called an antenna oscillator, and the antenna structure directly excited by high-frequency current is called an active Vibrator, otherwise called passive vibrator; existing vibrator, including physical vibrator and microstrip vibrator, when designing the antenna according to the needs of actual use, in order to make the resonant frequency point of the antenna meet the set requirements, it is necessary to adjust the resonant frequency point of the antenna The input impedance is adjusted. The adjusted oscillator and the ordinary oscillator still cannot meet the requirements of the current communication standard. The current communication standard is getting higher and higher, and the requirements for the microstrip oscillator are also getting higher and higher. The gain and directivity of the current oscillator , front-to-back ratios need breakthroughs, and the most important thing is to achieve the above-mentioned breakthroughs under the premise of miniaturization
