Abstract: A conformal lens-reflector antenna system in which a radio frequency (RF) reflector is disposed in a depression in a raised portion of a dielectrical RF lens. The RF reflector can be shaped to reflect RF signals between an RF feed path to the lens and a body of the lens that extends generally laterally away from the raised portion. RF signals having a frequency within a resonant frequency range of the lens can be directed along the RF feed path to the reflector, which can reflect the RF signals into the body of the lens from which the RF signals can radiate. Similarly, RF signals in the resonant frequency range of the lens in space near the lens can resonate in the lens, and the reflector can reflect those signals down the RF feed path.
