Design method and device of ultra-wideband antenna

Abstract

The invention relates to a design method and device of an ultra-wideband antenna, computer equipment and a storage medium. The method comprises the following steps: based on an input antenna model, obtaining an endpoint preset value of the antenna model; loading the antenna model according to a preset rule to obtain an optimal feed point value of the antenna model; based on the antenna model, segmenting the antenna model into a plurality of simulation material blocks; obtaining an optimal gradient curve of the antenna model according to the distance value between each simulation material block and the optimal feed point value, an end point preset value and a preset optimization function; and transmitting the optimal gradient curve to an ink-jet printing controller to instruct the ink-jet printing controller to perform jet printing on the antenna substrate based on the optimal gradient curve to obtain the ultra-wideband antenna. The ultra-wideband antenna obtained by the method has the advantages of wider bandwidth broadening, faster time domain convergence and less high-frequency clutter noise.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a design method, device, computer equipment and storage medium of an ultra-wideband antenna. Background technique [0002] Ultra-wideband technology is an important emerging technology, which is characterized by short pulse, wide-band, anti-multipath, and anti-interference. Its application directions include precise positioning, ultra-wideband communication, and ultra-wideband radar systems. With the advent of the Internet of Things, the design of ultra-wideband antennas is more challenging; as we all know, the antenna bandwidth can be expanded by changing the format and shape of the antenna. Generally, the common ultra-wideband antenna systems are divided into traveling wave antennas and standing wave antennas: Wave antennas such as horn antennas and Vivaldi antennas use the shape gradient of the traveling wave direction to guide the traveling wave direction and reduc...

Problems solved by technology

[0003] However, although the method based on discrete resistor loading can simply and effectively increase the bandwidth, the discrete resistor placed on the surface of the antenna needs to slot the antenna, which will destroy the integrity of the antenna, and both the slot and the discrete resistor will produce Signal interference at a certain frequency; and this method requires the antenna to have a certain size, otherwise it is impossible to make enough slots and place enough discrete resistors, which limits the size of the antenna and also limits the upper limit frequency of the antenna's work; thus resulting in loading Limited capacity, unable to better realize ultra-wideband characteristics
