The constantly increasing demand of advanced sensors and communications systems aboard of military platforms (ships, UAVs, aircraft, land vehicles, etc.) requires a high number of antennas, covering a very wide frequency spectrum. At the same time, the new platform concepts, dictated by an Integrated Topside Design approach, impose a very high level of structural integration of the antenna systems. The overall platform is designed keeping into account many different parameters including Radar Cross Section (RCS), Electromagnetic Interference (EMI), vulnerability etc. From an antenna system point of view, this translates into the necessity of developing antennas easy to be structurally integrated into different platforms and capable of combining more RF functions into the same aperture. In other words: wide-band active electronically scanned array antennas, preferably in planar printed technology which allows low weight, low profile and low costs. In this contribution, the development of a 6–9 GHz prototype array of dual-polarized connected dipoles is presented and discussed in detail. An analysis of spurious common-mode excitation is carried out and a novel design of a resonance-free connected array is presented.
