abstract

  • A broadband 1-bit independently dual-polarized dual-beam reflectarray antenna (RA) based on a magneto-electric dipole (MED) unit cell is proposed. This unit cell employs four stubs, which can be short-circuited (SC) or open-circuited (OC) to independently control two orthogonal linearly polarized beams. The proposed unit cell exhibits a very wide reflection phase bandwidth from 31.5 to 54 GHz (54.1 %). The radiation characteristics of the RA are obtained analytically, using the aperture field approach. The proposed reflectarray achieves a 1.5dB gain bandwidth of 35 % from 32 to 45.5 GHz.
