Radiation beam scanning for leaky wave antenna by using slots
This paper provides an insight of a new, microstrip leaky wave antenna.
It holds the ability to continue steer its beam at a swapping frequency. This is done with acceptable impedance matching while scanning and very little gain variation.…
