Wide scanning conformal cone-borne phased array

Firstly, the paper designs a novel broad beamwidth microstrip antenna at 16GHz, whose 3dB beamwidth is up to 170 degrees. Then a conformal phased array on conical surface is designed by means of the present broad beamwidth microstrip antenna. To achieve effective beam scanning in whole elevation and rolling planes, the whole rolling plane has been divided into six sections. Numerical results show that the gains of the phased array are of slight difference while the beamwidths at large scanning angles along the axial direction are relatively broad. To ensure the performance of the phased array, choosing higher frequencies is considerable.
