Multi-Plane Frequency Scanning using a Leaky-Wave Antenna Array with Double-End Series Feeding Network

A multi-plane frequency scanning antenna structure is introduced as a low-cost and frequency-functional antenna system for applications such as radar, spectrum sniffing and realtime spectroscopy. The structure consists in a leaky-wave antenna array with double-end series feeding network, excited at its four corners according to a suitable switching sequence. The design of the frequency-scanning antenna structure is validated via fullwave simulation.
