Abstract
Official abstract text for this publication.
Methods and systems for receiving in-phase and quadrature (I and Q) radio frequency (RF) signals without a phase shifter utilizing a leaky wave antenna are disclosed and may include generating in-phase and quadrature signals using a leaky wave antenna coupled to one or more low-noise amplifiers (LNAs) on a chip and without a phase shifter. The RF I and Q signals may be communicated from the single leaky wave antenna using coplanar feed points and/or feed points on a top surface and a bottom surface of the single leaky wave antenna. The leaky wave antennas may be integrated on the chip, on a package to which the chip is affixed, and/or on a printed circuit board to which the chip is affixed. The RF I and Q signals may be amplified by the one or more LNAs and may down-convert the RF I and Q signals to baseband signals.
First claim
Opening claim text (preview).
What is claimed is: 1. A communications system comprising: a circuit coupled to a leaky wave antenna, wherein said circuit is operable to receive a radio frequency (RF) signal from said leaky wave antenna, and said circuit is operable to generate, from said RF signal, using said leaky wave antenna including at least two feed points, and without using a phase shifter, an in-phase RF signal and a quadrature RF signal. 2. The communications system of claim 1…
