Abstract :
This paper takes the idea of structure tapering and investigates the general effect of such tapering on the performance characteristics of the antenna. In particular, the effect of height, apex radius, and degree of exponential tapering on ellipticity, cross polarization rejection, and reflection coefficient is investigated.
