Switchless Reconfigurable Antenna Grid for Low-Loss Operation

The patent removes switches from the antenna array structure entirely, extracting the problematic switching function and replacing it with a feed-network-based reconfiguration approach. This eliminates switch-related losses while maintaining the ability to reconfigure antenna radiation patterns and frequencies through electronic control of feed circuits.

The patent replaces mechanical/electrical switches with an electronic feed network system that uses controlled impedance transformations and signal combining. This substitution eliminates the need for physical switching components between radiators, reducing loss and improving power handling capability.

The patent extracts switches from the antenna radiator interconnections and replaces them with a linear feed network approach. This maintains signal linearity by avoiding the non-linear characteristics of switch components while preserving reconfiguration capability through electronic control.

The patent substitutes switch-based reconfiguration with a linear network theory-based feed system that maintains signal integrity and linearity. The feed network uses linear impedance transformations and signal combining techniques that preserve waveform characteristics.

The patent segments the feeding function into multiple independent feed circuits, each capable of operating at different frequencies and controlling different subsets of antenna radiators. This segmentation enables broadband operation by allowing simultaneous excitation at multiple frequencies while maintaining manageable complexity through modular feed circuit design.

The patent transitions from a single-point feeding approach to a multi-dimensional feed network structure where feeds are distributed across the antenna array in both spatial and frequency dimensions. This enables broadband coverage by exciting the antenna at multiple frequency points simultaneously while maintaining controlled complexity through systematic network design.

The patent segments the antenna array into multiple independently controllable groups, each fed by separate RF feeds. This enables sophisticated radiation pattern control through selective excitation of different radiator subsets while managing complexity by organizing feeds into systematic groups that can be controlled independently.

The patent designs the feed network to provide multiple functions through a unified structure: frequency selection, radiation pattern control, and impedance matching are achieved through the same feed circuits. This multi-functionality reduces overall complexity by eliminating the need for separate control mechanisms for each function.
