## Abstract A small array composed of three monopole elements with very small element spacing on the order of λ/6 to λ/20 is considered for application in adaptive beamforming. The properties of this 3‐port array are governed by strong mutual coupling. It is shown that for signal‐to‐noise maximizat

## Abstract A planar array of dipoles, with collinear dipoles connected by lumped negative inductances, is simulated by the piecewise sinusoidal method of moments. Over a multi‐octave bandwidth, the gain is close to the area gain, which is a remarkable result. The non‐Foster couplings smooth out an

Adaptive arrays in mobile communications based on any arbitrary performance criteria have many problems in tracking the desired signal at di!erent interference angles relative to the desired one. To use the adaptive arrays e$ciently in mobile communications, we need a system which is independent of
