After fine-tuning the unit cell for the desired radiating region and steering angles, the miniaturized leaky-wave antenna
has been designed by cascading 11 unit cells.

Based on this model and refinements through method of moments electromagnetic simulations, the proposed CRLH leaky-wave antenna
has been characterized and designed at 10 GHz, with CPW configuration on a thin and flexible substrate which exhibits all functions and performances superior to the prior state of the art.
A 5-[Lambda]-long prototype microstrip leaky-wave antenna
, shown in Figure 8, has recently been applied to the problem.
In this framework, two-dimensional (2-D) leaky-wave antennas
(LWAs) provide versatile, low-profile, and low-cost solutions for achieving directive radiation patterns, in the form of conical scanned or broadside pencil beams .
