Title:
DISC ANTENNA SYSTEM
Document Type and Number:
WIPO Patent Application WO2000028618
Kind Code:
A9
Abstract:
A antenna system is provided, including a substantially annular antenna element (100) having an inner perimeter edge. The antenna system also includes a two-dimensional amplifier system (140) coupled to the inner perimeter edge of the antenna element. The two-dimensional amplifier system may comprise a plurality of one-dimensional amplifiers, each one-dimensional amplifier being coupled to the inner perimeter edge of the antenna element (100) at substantially equally spaced angular positions (110, 120, 130). The two-dimensional amplifier system may also comprise a two-dimensional field effect transistor. The antenna element and two-dimensional amplifier system are configured to either receive or transmit a wave having a carrier frequency and an electric field vector, the terminus of which traces a nonlinear path within a plane transverse to an axis of wave propagation at an angular velocity corresponding to a rotation frequency between the carrier frequency and zero.
