Dual polarized metal gradient slot antenna of L-shaped connector, array antenna and method

Abstract

The invention discloses a dual polarized metal gradient slot antenna of an L-shaped connector. The dual polarized metal gradient slot antenna comprises a metal antenna oscillator, a metal reflector and an L-shaped connector; the metal antenna oscillator is connected with the metal reflector, the wall penetrating part of the L-shaped connector is embedded into the cavity of one arm of the metal antenna oscillator, and the metal core of the L-shaped connector is in feed connection with the other arm of the metal antenna oscillator; the invention also provides an antenna array and a processing method of the antenna. The dual polarized metal gradient slot antenna of the L-shaped connector, the array antenna and method provided by the invention have the beneficial effects that the two polarization ports of the antenna can be arranged on a straight line that is the same as one polarization direction through adjusting the positions of the two polarization ports of the antenna, the problem ofT / R component installation at the rear end under the condition that the space between the dual polarization antenna units is relatively small is solved, and thus the antenna achieves the impedance bandwidth of 9:1 under the condition that the active standing-wave ratio is less than 3:1, and has extremely high engineer application value.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a double-wire polarized metal tapered slot antenna with an L-shaped connector, an array antenna and a method. Background technique [0002] With the development of radar technology, radar systems have higher and higher requirements on the performance of antennas, and the advantages of ultra-wideband antennas are highlighted. The metal tapered slot antenna is an ultra-wideband antenna that is widely used, and has the advantages of wide frequency band, high gain and good time-domain characteristics. Compared with the planar printed Vivaldi antenna, it has higher physical strength, simple feeding structure and lower processing cost. The coaxial feed structure with simple structure can remove the limitations of traditional Vivaldi antennas in the fields of multi-functional arrays and high-power radars; at the same time, the increase in the metal thickness of the antenna enables the antenna t...
