Pattern shaping of RF emission patterns
A metallic shaping plate located in the interior housing of a wireless device is disclosed. The metallic shaping plate may influence a radiation pattern being generated by a horizontal antenna array. The result may be an increase in the gain of the array.
1. An wireless device comprising:
an antenna array including a plurality of antenna elements, wherein two or more of the plurality of antenna elements are selectively coupled to a radio frequency feed port, wherein at least two of the plurality of antenna elements generate an omnidirectional radiation pattern;
a housing coupled to the interior of the device and enclosing the antenna array; and
a plurality of metallic shaping plates, wherein each of the shaping plates has a different configuration, and wherein the shaping plates cause a change in the omnidirectional radiation pattern generated by at least two of the plurality of antenna elements.
2. The wireless device of claim 1 , wherein the plurality of metallic shaping plates includes a first shaping plate of a first configuration and a second shaping plate of a second configuration, wherein the first shaping plate is positioned on top of the second shaping plate.
3. The wireless device of claim 1 , wherein the configuration of a shaping plate is based on a size of the shaping plate.
4. The wireless device of claim 1 , wherein the configuration of a shaping plate is based on a thickness of the shaping plate.
5. The wireless device of claim 1 , wherein the configuration of a shaping plate is based on a material of the shaping plate.
6. The wireless device of claim 1 , wherein the configuration of a shaping plate is based on a shape of the shaping plate.
7. The wireless device of claim 1 , wherein the plurality of metallic shaping plates are positioned on the interior surface of the housing apparatus.
