However, the dispersive beam-scanning makes the LWAs very difficult to be utilized in systems that require high-speed data transfer, wide band and high directive antennas.

Naturally combining the two technologies, a leaky-wave gap waveguide antenna and a dispersive prism, a low-dispersive gap-waveguide leaky-wave antenna is achieved, with a specific radiation direction that in this example is ϕ= 41°. The main radiation direction varies only ±0.5° from 11.5 to 13.0 GHz, with side-lobe levels lower than −13 dB. A 20% half-power gain-drop frequency bandwidth has been obtained.
