Abstract

The present invention provides a resistance loading miniaturization Vivaldi antenna for an electromagnetic radiation measurement system. The antenna comprises a dielectric substrate, a trough-line metal area arranged on the top layer of the dielectric substrate and a Z-shaped microstrip line and a chip resistor which are arranged on the bottom layer of the dielectric substrate. The Z-shaped microstrip line is formed by connecting the impedance conversion microstrip line, the coupling microstrip line and the impedance deployment microstrip line in order. Compared to the prior art, the resistance loading miniaturization Vivaldi antenna for the electromagnetic radiation measurement system reduces more than 50% in size and has the moderate gain, and has convenient processing, facilitates integration and satisfies the system application requirement through the PCB technology.

Description

technical field [0001] The invention relates to a miniaturized Vivaldi antenna, in particular to a miniaturized Vivaldi antenna for resistance loading of an electromagnetic radiation measurement system. Background technique [0002] In recent years, Vivaldi antennas have been widely used in communication and measurement systems, radar systems, and biomedical detection due to their wide operating frequency bandwidth, stable gain, symmetrical beam, easy integration, and simple structure. Since ultra-wideband antennas are usually used in various terminals, they must face requirements such as low profile, simple structure, and miniaturization. The trade-off between performance and size has become the focus of consideration. In fact, the traditional Vivaldi antenna is an end-fire traveling wave antenna, and the working frequency band is limited by the antenna aperture size. It is generally believed that the aperture width and antenna length of the tapered slot antenna should sati...
