  • Extended dielectric material tapered slot antenna
    Patent number: 6239761
    Abstract: A tapered slot antenna (20) includes a dielectric (22) with a metallization layer (24) deposited on one side. The metallization layer (24) is etched to the dielectric substrate (22) to form a tapered slot (26, 28, 30, 32). In order to tune the antenna 20), for example, such that the E and H field beam width are symmetrical, the (22) extends beyond the wide portion of the slot as a dielectric loading (26, 28, 30, 32). A microstrip feed line (40, 42, 44, 46) is formed by a metallization deposit on an opposing side of the substrate (22). The microstrip feed line (40, 42, 44, 46) extends across a narrow portion of the tapered slot (26, 28, 30, 32) and is configured to optimize the coupling between the microstrip feed line (40, 42, 44, 46) and the tapered slot antenna (20).
