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.

leaky-wave antenna," IEEE Trans.
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 [27].
