Abstract
Directional wide band antenna that may be utilized to enhance cell phone coverage within a building, and/or for signals intelligence collection (SIGINT). Includes a spiral antenna with feed-point configured to transfer energy to/from the antenna. Includes an energy absorbent backing and an energy absorbent siding coupled with the spiral antenna. Includes a cavity behind the log-spiral slot antenna and in front of the energy absorbent backing. Includes a cable connector coupled to a tapered microstrip line coupled to the feed-point wherein the tapered microstrip line is configured to transform the input impedance to the antenna impedance. Housed in a container configured to hold the above listed components. Energy absorbent siding, cavity and energy absorbent backing greatly reduces back lobes. Another embodiment has log-spiral shaped slots at an outer portion of the log-spiral slot antenna overlap with the energy absorbent siding and wherein the feed-point overlaps the cavity.
