Vivaldi antenna arrays for SKA

We present several broad band arrays of tapered slot antennas for use in a new generation phased array telescope. In specific, a four element linearly polarized 3-12 GHz array, a 3 element 0.8-2.5 GHz coupled array and a four element dual polarized 0.8-2.5 GHz array are discussed. Integration with L...

Description
Summary:We present several broad band arrays of tapered slot antennas for use in a new generation phased array telescope. In specific, a four element linearly polarized 3-12 GHz array, a 3 element 0.8-2.5 GHz coupled array and a four element dual polarized 0.8-2.5 GHz array are discussed. Integration with LNAs and coupling between elements is examined.
