Abstract： Due to the increasingly intense electronic warfare in modern warfare，antennas as communication hubs urgently need technological updates and iterations.Therefore，a polarized metasur face RTA antenna that integrates transmisson and reflection capabilities is proposed which can generate different responses when fed with electromagnetic waves of diferent linear polarizations，namely， transmittingleft circularlypolarized waves orreflecting x raypolarized waves.By rotating the magneto electric dipole structure，the phase of the antenna element can be controlld.In order to verify the performance of the proposed antenna，a 10×10 antenna array is designed and simulated for testing. The tests show that the antenna has excellent transmission performance and anti polarization isolation characteristics，and can adapt to various wireless communication application environments.
