II. DIELECTRIC LOADED EXPONENTIALLY TAPERED SLOT ANTENNA DESIGNThe ETS approach is also known as flared ding antenna, is among one of the most promising antenna satisfying all requirements described in the technical challenges 11. It is fundamentally a planar traveling wave antenna with end fire radiation. This antenna is the preferred candidate for Mm Wave applications due to its wide bandwidth, low cross polarization and highly directive patterns. A major advantage of this antenna type is that the wide bandwidth and maximum gain can be achieved using exponentially tapered profiles with nonconductor loading 12. The proposed dielectric scheme provides an interesting alternative. This antenna is integrated by using a single substrate. It is easy to fabricate and the bodily structure is compact 13. To eliminate the higher allege modes in the waveguide, the thickness of the substrate is restricted. The loaded dielectric slab in front of the antenna can be considered as a dielectric guiding structure excited by the exponential flare resulting in a wider beamwidth and maximum gain. The compa...
