Abstract
In the drive for the development of wideband array antennas for military applications, a well designed balun is essential to achieve overall antenna performance. However, for balanced antenna arrays to be driven effectively, antiphase element feeds are required at the correct impedance over multiple octaves. This paper summarises balun design options in microstrip and stripline for use with highly coupled dipoles giving a 4:1 bandwidth from 2.7-10.8GHz.
