Abstract :
Two types of tapered slotline antennas (TSA) have been studied. One type, which requires a fairly thin substrate, gives a radiation pattern of high gaussicity. For submillimeter wave-lengths, where the substrate is difficult to thin down, a sandwich type with thick substrate and superstrate has been studied. The radiation patterns for the sandwiched antenna are substantially improved when an elliptical lens is added.
