▎ 摘　　要

NOVELTY - The surface has a first patch layer attached on a first surface of a medium substrate. A second patch layer is attached to a second surface of the medium substrate, where the first surface and the second surface are squares that are arranged in parallel. A frequency selection structure is provided with a long rectangular patch and a short rectangular patch. A gap is formed between a gap of the long rectangular patches and the short rectangular patches to form a frequency passband. A wave absorption structure includes two long metal straight wires symmetrically arranged on a diagonal of the second face. An end of the two long metals straight wires is connected by an L-shaped graphene patch. The two short triangular patches are arranged close to the L-shape graphene patch, where length of the short triangular patch is greater than the length of a long triangular patch, and length of two long triangular patches is less than length of an L triangular patch. USE - Dual polarization-absorbing integrated graphene frequency selecting composite superstructure surface for an antenna cover of a double/multi-station radar communication system. ADVANTAGE - The surface provides a dual-polarization integrated graphene with strong adaptability for different incident electromagnetic wave and frequency selecting composite superstructure surface, so as to solve the problem that the antenna cover based on the current frequency selection surface cannot well realize the hidden body of the radar antenna. The surface can make the antenna to resonate at the 9.7 GHz and 19.35 GHz the suction band, it keeps high transmission characteristics the 12.44 GHz band to the 17.54 GHz, and it can realize the wave absorption on two sides of the pass-band, at the same time, satisfy advantages of bipolar, low insertion loss and so on. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an antenna cover. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of the dual polarization-absorbing integrated graphene frequency selecting composite superstructure surface.
