Abstract

We propose an integrated small ultra-wideband antenna subarray module with narrow elevation pattern for future use in antenna arrays providing spatial processing capabilities such as Direction-Of-Arrival estimation in the azimuth plane, in the frequency range from 5 GHz to 8 GHz. The proposed subarray design is based on four mutually coupled Vivaldi antennas stacked on a common substrate in the E-Plane, with an element distance of delem 0;high=2. We optimize the antenna element in an infinite unit-cell stick array configuration and show that - in contrast to general believe - the truncation e ects when reducing the infinite stick-array to only four elements even reduce the total scan element reflection for broadside excitation. In addition, in contrast to most previously published E-Plane Vivaldi arrays, our design does not need a parallel-plate to microstrip balun at the feed point of each antenna element to realize an integrated planar feed network. Instead we use a novel ultra-wideband and geometrically small hybrid ring coupler to realize the array feed network directly in parallel plate technology, resulting in a low-cost, two-layer, single printed-circuit board integrated subarray module with narrow elevation pattern, operating from 5 GHz to 8 GHz.
