Abstract

The invention relates to an ultra wide band symmetric biconical antenna, in particular relates to an ultra wide band symmetric biconical antenna with a compound curve as a bus, which aims to solve the problem that the size and the weight of a biconical antenna cannot give consideration to both the high-frequency characters and the low-frequency characters. The ultra wide band symmetric biconical antenna comprises two frustum bodies, wherein the two frustum bodies are in a shape of a hourglass from top to bottom, each frustum body consists of a first frustum body with a binomial curve as a bus and a second frustum body with a straight line as a bus, and the top surface of the first frustum body and the bottom surface of the second frustum body are connected to form a whole body. The ultra wide band symmetric biconical antenna is used for the field of wireless communication.

Description

technical field [0001] The invention relates to an ultra-wideband symmetrical biconical antenna, in particular to an ultra-wideband symmetrical biconical antenna whose busbar is a compound curve, and belongs to the field of wireless communication. Background technique [0002] At present, UWB technology is an important development direction in the field of wireless communication, and has become one of the hot issues and research directions in the field of communication at home and abroad in recent years. The reason why ultra-wideband technology has been widely concerned is mainly because of its advantages such as high transmission rate, low loss and large information capacity. The development of ultra-wideband technology also makes the design of ultra-wideband antennas more and more important. Up to now, various forms of ultra-wideband antennas have been proposed, and many of them have been used in practical projects. [0003] As a common ultra-wideband antenna, biconical a...
