Design Of A Novel Conformal Leaky-Wave Antenna (Clwa) On A Convex Surface For Ku Band

This research demonstrates the capability to conform a Substrate Integrated Waveguide Conformal Leaky-Wave Antenna (SIW-CLWA) design, which ensures an enhanced efficiency in the Ku band, with better return loss curve in terms of its shape and trend. This design employs a substrate called ROGER RT DUROID 5880 and is comprised of 7-unit cell patches. The designed Antenna is analyzed for its radiation pattern. The narrow band of the proposed CWLA in the Ku band is acquired at the frequency of 14.56GHz with gain dB of -53.147. Compared to the existing Goubau-line leaky-wave antenna, the proposed CLWA gives an enhanced result in the Ku band in terms of frequency and gain. The measured return loss is 10dB better compared to the existing Antenna design.
