Description

technical field [0001] The invention relates to an adaptive multi-band integrated impedance matching network double-ridge horn antenna, which belongs to the technical field of antenna equipment. Background technique [0002] At present, the double-ridge antenna is widely used in daily life, military communication and other fields, but it is found in actual use that when the current double-ridge antenna is small in size, it often cannot operate according to the frequency of the communication signal. Flexibly adjust the adaptability of the double-ridge antenna signal for sending and receiving, and at the same time, it is easy to cause relatively poor stability of the communication signal. If it is necessary to enhance the signal adaptability of the double-ridge antenna and the sensitivity of adapting to different signals, it is necessary to increase the equipment of the double-ridge antenna structure, thus seriously affecting the flexibility and reliability of the double-ridge...

[0002] At present, the double-ridge antenna is widely used in daily life, military communication and other fields, but it is found in actual use that when the current double-ridge antenna is small in size, it often cannot operate according to the frequency of the communication signal. Flexibly adjust the adaptability of the double-ridge antenna signal for sending and receiving, and at the same time, it is easy to cause relatively poor stability of the communication signal. If it is necessary to enhance the signal adaptability of the double-ridge antenna and the sensitivity of adapting to different signals, it is necessary to increase the equipment of the double-ridge antenna structure, thus seriously affecting the flexibility and reliability of the double-ridge antenna, and seriously affecting the development of double-ridge antenna technology. At the same time, it lacks an effective enhancement effect on the signal with severe attenuation after long-distance transmission, which leads to poor stability of the communication signal. Therefore, in view of this situation, it is urgent to develop a new type of double-ridge antenna to meet practical needs
