Abstract
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. Further, the antenna may simultaneously allow/provide spec-compliant Global Positioning System operation and spec compliant Height of Burst operation.
