Abstract
A wide band, integrated linear printed antenna array with low sidelobe cosecant square-shaped beam pattern is presented. Array synthesis mainly about the wide shaped coverage, low ripple and sidelobe level (SLL) has been done using the modifled least square method by matrix inversion. A printed dipole integrated with wideband balun has been chosen as the array element for wide bandwidth and good integration with the feeding network. Simulated results have shown good agreement with the measured results of the antenna array, which has a VSWR • 1:3 bandwidth 15% and good pattern with cosecant square-shaped region beyond 30 - and SLL • i27dB in L-band.
