- Abstract
- A dual-band dual-polarization array antenna for an advanced multi-function radio function concept (AMRFC) radar application operating at S- and X-band is proposed. To improved bandwidth of S-band, the proposed antenna uses the modified coupling feed patch. The simulated bandwidth (VSWR 2) of the array antenna is 20 % and 30.7 % for the S- and X-band, respectively. The simulated isolation between the two orthogonal polarizations for both bands is better than 15 dB. The simulated cross-polarization level is less than 18 dB for the S-band and less than 21.7 dB for the X-band.
