Abstract

In this paper, a two-dimensional slotline coupling structure combined with E and H-plane slotlines is proposed for the oscillator-type phased array antenna. The proposed structure provides the two-dimensional scanning capability with smaller size and less spurious radiation than the conventional radiation or transmission line coupling structures. These operating characteristics are analyzed and experimentally demonstrated.
