In order to enable multifunction arrays with simultaneous transmit and receive, high isolation must be provided between antenna elements. This isolation should ideally be independent of the waveforms being transmitted. In this paper, a tunable baffle design is presented which provides over 30 dB of improvement in isolation for bandwidths of 7.5 MHz between adjacent antennas. This isolation can be...
A small three element linear planar array designed to have high isolation between elements for Simultaneous Transmit And Receive (STAR) is demonstrated. This high isolation is achieved through use of tunable resonators that control the near fields of the array without detrimentally affecting the radiated fields. These resonators, which are placed between the patch antenna elements of the array, provide...
