Abstract

The invention discloses a miniature printing logarithmic cycle antenna based on unit bending. The antenna comprises the components of a dielectric substrate, a feeding unit, a plurality of radiating units with different lengths, and double parallel lines which are connected with the plurality of radiating units. Each radiating unit comprises a top-layer radiating unit and a bottom-layer radiating unit. The radiating units are arranged on the upper surface and the lower surface of the dielectric substrate according to a length sequence. The top-layer radiating unit and the bottom-layer radiating unit are respectively arranged on the upper surface and the lower surface of the dielectric substrate. The dimensions and the structures of the top-layer radiating unit and the bottom-layer radiating unit in each radiating unit are same. The top-layer radiating unit and the bottom-layer radiating unit in each radiating unit are symmetrical relative to the two parallel lines. The miniature printing logarithmic cycle antenna can realize the broadband antenna with excellent matching. According to the miniature printing logarithmic cycle antenna, the transverse dimension of the antenna is greatly reduced through bending an oscillator, and furthermore antenna performance basically does not reduce, thereby realizing miniaturization of the printing logarithmic cycle antenna.

Description

technical field [0001] The invention relates to the technical field of radio frequency antennas, in particular to a miniaturized printed logarithmic periodic antenna based on unit bending. Background technique [0002] The printed logarithmic periodic dipole antenna is a frequency-invariant structure with broadband and wide-angle characteristics, and its structure is simple and easy to process. It is widely used in array antennas for radar and communication reconnaissance systems. The antenna adopts printed circuit technology, and the radiation oscillator is printed on both sides of the dielectric substrate. [0003] Since log-periodic antennas are often used for indoor distribution and elevator signal coverage, the use of log-periodic antennas is severely limited due to their large structural size, and there is a problem of large size of traditional printed log-periodic antennas. Contents of the invention [0004] The technical problem to be solved by the present inventi...
