Abstract :
The effect of dielectric superstrate on a linearly tapered slot antenna (LTSA) was investigated experimentally. It was observed that the dielectric superstrate improves the directivity but generally at the expense of higher sidelobe level. It improves the patterns and directivity of the antenna by increasing the electrical length and effective aperture of the antenna. The dielectric superstrate could be used to reduce the physical length and to improve the radiation characteristics of the LTSA.<>
