Abstract

The invention relates to an ultra-wide band printed dipole antenna, in particular to an ultra-wide band printed dipole antenna with combined semicircular sheet oscillators capable of realizing balanced microstrip line feeding. The ultra-wide band printed dipole antenna solves the problems of poor balanced feeding performance and poor directional pattern symmetry of the existing planarized, band-ultra-widened and miniaturized ultra-wide band antenna. A left oscillator and a right oscillator of combined semicircular symmetrical oscillators are symmetrically printed on the upper surface of a dielectric plate along the centerline of the dielectric plate. A balanced microstrip line upper patch is printed on the upper surface of the dielectric plate along the length direction of the centerline of the dielectric plate. A balanced microstrip line lower patch is printed on the lower surface of the dielectric plate along the length direction of the centerline of the dielectric plate. The lower end of the balanced microstrip line lower patch is in contact with the lower edge of the dielectric plate. A metallized via is connected with the upper end of the balanced microstrip line lower patch through a metal sheet. The ultra-wide band printed dipole antenna is used for receiving and transmitting radiation signals.

Description

technical field [0001] The invention relates to an ultra-wideband printed dipole antenna, in particular to an ultra-wideband printed dipole antenna with a balanced microstrip line feeding combination semi-circle vibrator. Background technique [0002] The original form of ultra-wideband (Ultra-Wide Band, UWB) technology is pulse wireless communication, which originated in the 1940s. From its appearance to the 1990s, UWB technology was used as a military technology in communication equipment such as radar and low interception rate. used in . In the research of time-domain electromagnetics in the 1960s, ultra-wideband technology was used to completely describe the instantaneous characteristics of a certain type of microwave network through the impulse response. The US OSD / DARPA (The Defense Advanced Research Project Agency and the Office of the Secretary of Defense) proposed and was approved by the UWB Group, and first defined the concept of "ultra-wideband".
