This paper presents a method with which to calculate the maximum scan error due to phase quantization in the visible region of dense phased arrays. The scan error is expressed as a function of the density ratio and the number of bits being used for digitization. A closed-form expression is derived with which the maximum scan error as well as the maximum scan range in the visible region of the array...
The progress on the design of a dual-polarized dense dipole array was presented. A wide bandwidth has been realized and good cross-polarization performance for an element embedded in the infinite array has been demonstrated.
This paper presents preliminary results of a Dense Dipole Array (DDA) design. The array consists of tightly coupled dipole elements above a ground plane and fed differentially through a specially designed common-mode suppressing feed. Measurements of a 4 × 4 prototype indicate an impedance bandwidth of ≈ 2:5 ∶ 1.
