Design of E-Band Common Aperture Dual Polarization Terminal Antenna

In this paper, a co-aperture terminal antenna works in the E band is proposed. The antenna is composed of substrate integrated wave-guide(SIW) cavity antenna and printed dipole antenna. The public bandwidth of the antenna array reaches 13.3%. The maximum gains of vertical and horizontal polarizations are 9.89dB and 10.38dB, with the scanning angle from -40° to 40° for vertical polarization and the scanning angle from -52 ° to 52 ° for horizontal polarization with gain deterioration less than 3 dB.
