In this paper, several conformal leaky-wave antennas (CLWAs) are designed, which utilize backward radiating waves to focus the beam. They employ a metal strip grating (MSG) in order to introduce the required phase constant ($\beta$) on a curved aperture to compensate for the defocusing due to the curvature. The required $\beta$ is obtained by modulating the distance between adjacent strips/slots to...
A leaky-wave antenna (LWA) is a traveling wave antenna that uses a fast wave as the main radiating mechanism, which radiates continuously along the structure. Depending on the length of the antenna, the fast wave may get reflected from the termination, which causes another beam in the opposite direction. The effects of the reflected fast wave on the radiation pattern can be analyzed if the reflection...
