A High Sensitivity Intelligent Feedback Double Ridge Antenna

Abstract

The invention relates to a high-sensitivity intelligent back-feed type double-ridged antenna, and the antenna comprises a power divider, a frequency detection device, a frequency detection device, a numerical control attenuator, a numerical control phase shifter, a signal receiving and transmitting device, a double-ridged wave antenna, a protection housing, guide plates, and a control circuit. The power divider, the frequency detection device, the numerical control attenuator, the numerical control phase shifter, the signal receiving and transmitting device, the double-ridged wave antenna and the control circuit are all located in the protection housing. A part, corresponding to the double-ridged wave antenna, of the protection housing is provided with a conduction hole. The number of the guide plates is not less than two, and the guide plates are hinged to the protection housing in a manner of surrounding the axis of the conduction hole through an adjustment device. The antenna can effectively improve the application flexibility and reliability, can automatically carry out adaptive adjustment according to the change of communication signal frequency, and effectively improves the application flexibility and the signal reliability.

Description

technical field [0001] The invention relates to a high-sensitivity intelligent feed-back double-ridge 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, which seriously affects the flexibility and reliability of the double-ridge antenna, and seriously af...

[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, which seriously affects the flexibility and reliability of the double-ridge antenna, and seriously affects the development of double-ridge antenna technology. Therefore, in view of this situation, it is urgent to develop a new type of double-ridge antenna to meet the needs of actual use.
