Conformal aperture coupled microstrip phased array on a cylindrical surface

A C-band conformal aperture coupled microstrip patch phased array was modelled and fabricated. The measured results show the capability of the array to form a directive sector beam as well as an omnidirectional pattern within the measured bandwidth of 19%. As the gain variation is negligible while scanning the direction of the array, it is recommended for 360/spl deg/ cover in communication systems.
