The present invention is a device which includes an antenna and circuitry. The antenna may receive a circularly-polarized signal as first and second linearly-polarized signals. The circuitry is connected to the antenna and is configured for combining the first and second linearly-polarized signals to produce at least two reception patterns. The reception patterns are created by summing the first and second linearly-polarized signals via phase shifting. The reception patterns are optimized for at least two substantially different directional orientations....
What is claimed is: 1. An assembly, comprising:a housing;a substrate, the substrate being connected to the housing to form a cavity;a plurality of chip antennas, the plurality of chip antennas being connected to the substrate and being at least substantially disposed within the cavity;circuitry, the circuitry being connected to the substrate, the circuitry further being connected to the plurality of antennas; andpotting material, the potting material being disposed within the cavity and at least substantially filling the cavity,wherein the assembly is co...
