Microstrip broadband phased array elements

Microstrip patch antenna arrangements offer many advantages. They provide low profiles, are light-weight and are easily integrated with the monolithic circuitry that has been embraced for miniaturised RF sensing systems. This paper presents the designs of 8-16 GHz bandwidth log-periodic and aperture-stacked based antenna arrangements. These antennas are examined in the light of the existence of alternatives (e.g., a Vivaldi tapered slot sensor) for operation as broadband sensing elements.Hedley J. Hansen, Michael E.
