Investigations on Tapered Dielectric Slab Antenna

From this book it has been also observed that tapers in both wave launching and free space radiating edges are useful in simultaneous impedance matching and improvement of the radiation pattern. The introduction of pyramidal taper in the front radiating face with adjustable properties (length and base area of the introduced pyramidal taper section) can give similar directive beam without undesirable increase in length and at the same time it shows dual frequency operation. An appropriate approach of truncation in the front radiating edge with adjustable properties (length and base area of the truncated pyramidal hollow section) can give improved directive beam without undesirable increase in length and at the same time huge improvement in bandwidth and impedance matching. For the limitation of fabrication facilities, this truncated front truncated pyramidal dielectric slab antenna could not be studied experimentally so far. Even better performance may be obtained by stepped truncation of the radiating aperture creating an array of additional apertures. All these give our proposed antenna competitive advantage for trans-receiver applications over standard dielectric slab antennas.
