Abstract
A compact and flat antenna that provides both Direct Broadcast Satellite and local off-air reception. The flat reflector is made of a composite material with multiple reflective radiating surfaces. The multi-stepped reflector combines both diffraction and refractive principals to collimate Radio Frequency signal waves to a short focal point. At the focal point a phase correcting splash plate and lens direct the RF signal through a low loss axis-fed circular waveguide and then to a low noise amplifier. This compact design reduces space, cost and over-all structure, which presents an aesthetically pleasing satellite communication antenna. The antenna aperture includes a VHF/UHF antenna element for reception of local and/or off-air broadcast TV signals eliminating the need and cost to install a separate antenna.
