“…In [7][8][9][10][11], newly designed comparator networks and phase-controlled antenna arrays are used, whereas the feeding networks become fairly complicated. Multiport antennas proposed in [4] and [12][13][14][15] show great potential to obtain a sum-difference beam with miniaturized geometries. A four-port folded dipole pair is presented in [4] to realize desired monopulse pattern, but additional comparator network is required.…”

“…The null steering capabilities of a multiple mode array and potential enhancements to phased array performance have been previously investigated [76,77,71,36]. The primary advantages in the multiple mode beam steering approach presented here are the reduction of unwanted mutual coupling and an increase in array scan range.…”

“…The parameter φ f = π 2m is the required angular separation between feed points for optimal CP pattern quality as function of the mode number m. Shorting vias provide an additional design parameter to achieve the desired radiation pattern over a wide range of patch dimensions [69]. This is particularly important when concentrically collocating these antennas in a nested configuration for null and beam steering as investigated in [71]. The analytical equations presented in [69] were used to derive initial design parameters for each of the 4 SARP antennas.…”
