The systematic design of broadband, directive, scanned planar leaky-wave antennas using coupled-cavity substrate integrated waveguide technology is reported in this work. The design methodology is based on the optimization of the corresponding transverse resonance phase equation, so that a constant scanning angle condition is satisfied for a wide frequency band. This design process is validated with...
A wireless power transfer system is conceived to empower light drones and unmanned aerial vehicles. To satisfy the power budget of the wireless link and provide enough power to the drone, new circuits based on directive frequency-scanned leaky-wave antennas and circuits are proposed. It is shown how the proposed leaky-wave devices introduce enough gain in the receiver system, while assuring reception...
