Latest Patents

One of Roscoe's latest patents is the Closed Loop Antenna Tuning System. This tunable resonant system includes an electric element and a core with a controllable parameter that determines the resonant frequency. To tune the system to a desired frequency, a low power, narrowband signal is applied to the electric element. The reflected or transmitted power is measured, and the controllable parameter is adjusted to minimize the reflected power in a closed loop.

Another significant invention is the Low Profile Mobile Satellite Antenna. This antenna features high gain at low elevations, making it suitable for satellite communications. It consists of a helical loop with tightly spaced turns to provide strong coupling. The helical loop behaves like a travelling-wave loop antenna, with a typical pitch of 1 to 2 degrees.
