Problems solved by technology

[0003] The combination of helical antenna and LTCC technology makes the helical antenna planar. However, in the prior art, in the high frequency band of W-band, the helical antenna using LTCC technology is limited by the processing technology, so that the radiation pattern of the antenna changes from axial to The radiation pattern is split into a conical radiation pattern, the axial gain and axial ratio are greatly deteriorated, and the condition of axial radiation cannot be satisfied

Abstract

A helical antenna unit based on a low temperature co-fired ceramic (LTCC) medium and enabling a directional diagram to be corrected is in a medium integration waveguide feed mode. A center spiral radiating body is a main radiation part of an antenna, and a surrounding medium-integrating cone-shaped horn corrects a radiating directional diagram of the antenna. The antenna unit works at a W waveband, good impedance and axial ratio bandwidth can be obtained, and a cone-shaped radiating directional diagram can be effectively restrained within available machining accuracy.

Description

technical field [0001] The invention relates to a helical antenna unit, in particular to a W-band LTCC helical antenna unit with pattern correction. Background technique [0002] In the millimeter wave frequency band, circularly polarized antennas have great benefits in improving signal transmission quality, so they are widely used. Among these circularly polarized antennas, the helical antenna has been widely used due to its unique wide axial ratio bandwidth and wide impedance bandwidth. Especially since the low-temperature co-fired ceramic (LTCC) technology was produced, it has provided convenient dielectric conditions for the planarization of various antennas. [0003] The combination of helical antenna and LTCC technology makes the helical antenna planar. However, in the prior art, in the high frequency band of W-band, the helical antenna using LTCC technology is limited by the processing technology, so that the radiation pattern of the antenna changes from axial to Th...
