The invention discloses a honeycomb ultra-wideband high-gain hexagonal array dielectric lens, which comprises a discrete dielectric lens and a feed source antenna, and is characterized in that the discrete dielectric lens comprises a plurality of dielectric unit structures distributed in an array; each medium unit structure comprises an air column, a medium column and a cross-shaped medium column which are arranged in sequence, the air column and the medium column are both in a regular hexagon shape, one end of the medium column is provided with a regular hexagon groove structure, the air column is located in the regular hexagon groove structure of the medium column, and the cross-shaped medium column is located between the air column and the medium column. And one end of the cross-shaped dielectric column is connected with one end of the dielectric column far away from the air column. The invention provides a biological bionic honeycomb-shaped ultra-wideband high-gain hexagonal array dielectric lens, which can realize the conversion of electromagnetic waves from spherical waves to plane waves, realize the conversion of linear polarization and circular polarization at the same time, and also realize the gain improvement of an antenna gain in a large frequency band width.
Description
technical field [0001] The invention belongs to the technical field of microwave passive devices and microwave communication, in particular to a honeycomb ultra-wideband high-gain hexagonal array dielectric lens. Background technique [0002] The polarization state of electromagnetic waves is an important characteristic of electromagnetic waves, which is characterized by the time-varying characteristics of the orientation of the electric field intensity vector at a given point in space, and is described by the time-varying trajectory of the endpoints of the electric field intensity vector, including linear polarization, circular There are three types of polarization, polarization and elliptical polarization. In many cases, the polarization direction of electromagnetic waves plays a very critical role in practical applications, and this characteristic is used in reflector antennas, imaging systems, sensors, and antenna radomes. Traditional electromagnetic wave polarization c...
