Abstract :
New tapered slot antennas with Fermi-like profiles are introduced and their radiation patterns are studied theoretically and experimentally. It is shown that by widening the slot at the beginning of the taper, the E-plane HPBW becomes narrower and H-plane HPBW becomes wider compared to the case when the slot mainly opens at the end of the taper. A new CPW triangular impedance transformer combined with an in-line transition to slot-line with radial balun is used for feeding the antenna.
