Abstract

The present invention relates to a strip line-fed cross-shaped slot double-circularly-polarized linear array. The linear array comprises a metal cavity and a first metal conduction band; the first metal conduction band is located inside the metal cavity; the metal cavity is provided with a metal cavity upper cover plate and a metal cavity lower bottom plate; the first metal conduction band is arranged in parallel with the metal cavity lower bottom plate; two ends of the first metal conduction band are bent downwards and pass through the metal cavity lower bottom plate so as to be adopted as a laevorotation feeding port and a dextrorotation feeding port respectively; and more than two cross-shaped slots are formed evenly in the metal cavity upper cover plate; a microstrip plate is arranged above the metal cavity upper cover plate; one side surface of the microstrip plate, which is corresponding to the cross-shaped slots, is provided with more than two metal patches; the metal patches are in one-to-one correspondence with the cross-shaped slots; the vertical projection of the geometric center of any one metal patch on a plane where the first metal conduction band is located, is a central projection; and the direction of the axis of the first metal conduction band deviates from the central projection.

Description

technical field [0001] The invention relates to the technical field of phased array antennas, in particular to a double-circularly polarized linear array with line feeding and cross-slotted cross slots. Background technique [0002] Array antennas are widely used in mobile communication fields such as airborne, ship-borne, and vehicle-mounted. In order to meet the requirements of mobile carriers for wind resistance, array antennas are required to be low-profile and miniaturized. Low-profile panel antennas can be implemented in two forms: oblique beam panel array and phased array antenna, both of which have been widely used and have their own advantages. Phased array antennas are divided into one-dimensional electronic scanning and two-dimensional electronic scanning. The cost of the former is relatively low. In the field of mobile satellite TV, especially when the requirements for antenna gain are high, the price advantage of one-dimensional electronic scanning is more obvio...
