Abstract: A broadband quadruple helical circularly-polarized antenna for receiving circularly polarized GNSS signals includes a dielectric cylinder oriented along a vertical axis; four spiral conductors wrapped around the cylinder; the four spiral conductors divided into an upper longitudinal section and a lower longitudinal section; and inductors connecting corresponding spiral conductors of the top and lower longitudinal sections. The spiral conductors in each section have a constant winding angle around the cylinder. The winding angle of all of the conductors in the same longitudinal section is the same. The winding angle of the upper longitudinal section is smaller than the winding angle of the bottom longitudinal. An excitation circuit is connected to the conductors. A third longitudinal section is below the lower longitudinal section, wherein the third longitudinal section includes conductors wound in an opposite direction relative to the lower longitudinal section.

Abstract: A computing device with a configurable antenna. The antenna is configured through a switching circuit operating under software control. Operating characteristics of the antenna are configured based on connections between conducting segments established by the switching circuit, allowing the nominal frequency, bandwidth or other characteristics of the antenna to be configured. Because the switching is software controlled, the configurable antenna may be integrated with a software defined radio. The radio and antenna can be reconfigured to support communication according to different wireless technologies at different times or to interleave packets according to different wireless technologies to support concurrent sessions using different wireless technologies.

Abstract: A broadband quadruple helical circularly-polarized antenna for receiving GNSS signals comprises an excitation circuit and a set of quadruple spiral elements. Each quadruple spiral element consists of four conductors. Each conductor is a one spiral turn of the quadruple spiral element. Said conductors have equal winding angle. The winding angle of all conductors does not change in the same quadruple spiral element. Conductors of neighboring (longitudinally) quadruple spiral elements have different winding angles. The antenna provides a sharp drop in AP at angles near the horizon and a small AP level in the lower hemisphere.
