Analysis of the EMBRACE aperture array antenna by the characteristic Basis Function Method

This paper describes the use of the Characteristic Basis Function Method for the simulation of large phased array antennas for radio astronomy. It will be shown how the antenna effective area and the receiver noise temperature depend on array size. Also the receiving sensitivity A

_sys
normalised with respect to the physical area of the array will be shown for different array sizes and scan angles.
