From: Wide-angle scanning planar array with quasi-hemispherical-pattern elements
Simulated and measured scanning gains of the proposed linear and planar arrays at 5.8 GHz. Scanning patterns’ maximums of the linear arrays locate closed to the end-fire directions instead of the broadside direction, this characteristic can compensate the attenuation factor cos(θ) of planar array, which makes the directivity of planar array decays not too much when beam scans to end-fire directions.
