Dual-Band Array Antenna Layout for Wide-Angle Gain Stability

The antenna array is divided into multiple independent sub-arrays, each with its own feeding network. This segmentation allows each sub-array to be optimized independently while collectively achieving the desired gain performance at maximum scan angles without requiring an excessive total number of elements.

The patent transitions from a traditional single-plane array configuration to a multi-layer three-dimensional array structure. By distributing array elements across multiple dielectric layers and utilizing vertical spacing, the effective aperture is increased without proportionally increasing the number of elements, thereby maintaining gain at wide scan angles.

The total power requirement is segmented and distributed across multiple independent array elements and sub-arrays. Instead of concentrating high power in fewer elements, the system uses more elements at lower individual power levels, which disperses heat generation and reduces peak operating temperatures while maintaining total system capacity.

The patent introduces intermediate power amplification stages and impedance matching networks between the signal source and array elements. These intermediary components optimize power distribution and reduce inefficiency-induced heat generation, allowing the system to achieve required capacity with lower overall power dissipation.

The array is segmented into multiple sub-arrays with independent feeding networks, allowing heat dissipation to be distributed across multiple localized regions rather than concentrated in a single large array. This segmentation maintains total gain while improving thermal management efficiency.

By transitioning to a multi-layer three-dimensional configuration, the heat dissipation volume is increased without proportionally increasing the number of active radiating elements. The additional vertical dimension provides more space for thermal management while maintaining the effective aperture needed for high gain.
