Phaser-based feeding network for uniformly scanning antenna arrays

The paper proposes a phaser-based differential feeding network for uniformly scanning antenna arrays. The feeding network is composed of a Wilkinson power divider connecting a phaser in one branch and a TEM transmission line in the other branch. An example of an antenna uniformly scanning from -60 degree to 60 degree within the frequency range of 4-6 GHz is presented for illustration.
