CPW-Fed Slot Antenna for Wideband Applications A new coplanar waveguide (CPW)-fed wideband printed slot antenna is presented, and the impedance characteristics of this antenna with different sizes of tapers are discussed. The effect of tapering angle with the resonant frequency is also observed. INTEGRATED TAPERED SLOT ANTENNA ARRAYS AND DEVICES Endfire antenna elements of the tapered slot antenna (TSA) type can be employed both as single elements and in arrays. TSAs utilize a tapered slot in the metalization on a thin dielectric substrate, to radiate in the "end-fire" direction (along the tapered slot, see Figure 1). The special case of air dielectric also has been investigated.
