Effect of a reactive loading in microstrip leaky wave antennas
Résumé
The influence of capacitors periodically soldered along the radiating edges of a leaky wave antenna (LWA) is described. As the propagation characteristics are modified, the main beam is tilted from the angle observed for the unloaded LWA. This property allows beam steering applications at a fixed frequency if bias-controlled reactances are used.
