Abstract

A printing log-periodic antenna provided with a V-type oscillator relates to a printing-type log-periodic antenna and specifically relates to a printing log-periodic antenna provided with a V-type oscillator. The printing log-periodic antenna provided with the V-type oscillator is provided by the invention for solving the problem that the modern communication and electronic system is getting miniaturized gradually and the size of an ordinary printing-type log-periodic antenna is too large. The printing log-periodic antenna provided with the V-type oscillator comprises a dielectric substrate, a front side center micro-strip line, a back side center micro-strip line, a first branch micro-strip line with eight front sides, a second branch micro-strip line with eight front sides, a first branch micro-strip line with eight back sides and a second branch micro-strip line with eight back sides; the front side center micro-strip line is printed in the middle of the front side of the dielectric substrate and two ends of the front side center micro-strip line are respectively connected to two ends of the dielectric substrate; and the back side center micro-strip line is printed in the middle of the back side of the dielectric substrate and two ends of the back side center micro-strip line are respectively connected to two ends of the dielectric substrate. The printing log-periodic antenna with the V-type oscillator provided herein is applied to the wireless communication field.

Description

technical field [0001] The invention relates to a printed logarithmic periodic antenna, in particular to a printed logarithmic periodic antenna with a V-shaped vibrator, which belongs to the field of wireless communication. Background technique [0002] The log-periodic antenna is a traditional broadband antenna, which has the advantages of wide impedance bandwidth, high in-band gain, and low sidelobe, and has become a research hotspot. With the help of printed circuit technology, the log-periodic antenna can be realized on a planar structure, and its low-cost mass production becomes possible. However, since modern communication and electronic systems tend to be more and more miniaturized, the size of the common printed logarithmic periodic antenna is too large, which greatly restricts its application. Contents of the invention [0003] In order to solve the problem that the size of the common printed log-periodic antenna is too large due to the trend towards miniaturizat...
