A high gain, steerable phased array antenna includes multiple oblong
slots. For each of the oblong and preferably rectangular slots, an
electrical microstrip feed line is disposed within a parallel plane to
the slot, and extends in the short dimension of the slot across the
center of its long dimension. The microstrip feed lines and corresponding
oblong slots form magnetically coupled LC resonance elements. A main feed
line couples with the microstrip feed lines. Delay circuitry is used to
electronically steer the antenna by selectively changing signal phases on
the microstrip feed lines. One or more processors operating based on
program code continuously or periodically determine a preferred signal
direction and control the delay circuitry to steer the antenna in the
preferred direction. The preferred signal direction is determined based
on a directional throughput determination.
