Design of a wide-band conformal phased array antenna with aperture-coupled antenna

A wide-band 9times4 conformal phased array antenna is designed with the aperture-coupled antenna in this paper. The array is assembled with 9 linear arrays. The elements in the each linear array are fed via apertures by a feed network which is integrated with the array. The proposed conformal antenna is easy to fabricate. Meanwhile, the elements are shielded with a dielectric layer on them. The measured result of the center embedded linear array shows the bandwidth over 20% (VSWR<2.0) and the cross-polarization level is below -20dB.
