Abstract
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.
