A high frequency device design and simulation results are reported for an 8 x 8 phased array of unit cells. Each unit cell comprises a (3 x 3) sub-array of 1/4 wave rod monopole radiators. Each unit cell is the basic building block that can be arranged to form 9 interpenetrating arrays. Each interpenetrating array comprises an independently addressable 8 x 8 array of 1/4 wave rod monopole radiators that fits into the lateral space of a single 8 x 8 array of patch radiators but can operate on 9 independent radio frequency channels within the same contiguous communication band without interference and can direct each radio frequency channel into independent directions simultaneously. The beamformer architecture, operation principle, and simulation results are presented and discussed, and an outline of its construction based on 2.5D integration is presented.
