Abstract :
A broadband modified Wilkinson power divider feed network for a 4 element antipodal Vivaldi antenna array in the frequency range of 2-6 GHz is presented. A modified Wilkinson power divider formed by implementing one radial stub on each branch is designed to meet the antenna specifications. Measured results are shown to meet the array specifications. This wideband array is useful in applications such as electronic warfare.
