20120319760 | RF PROXIMITY SENSOR - A sensor has a strip resonator filter that energizes an emitter patch which emits an electric field out from the strip resonator filter (away from the strip resonator filter). The capacitance of the filter, or specifically the coupling capacitance and radiation pattern of the slotted patch, is altered when an object such as a finger is near the sensor. Resulting changes in a signal outputted by the filter can be used to determine how close the object is to the sensor. The strip resonator filter may be a half wavelength strip resonator coupled filter having three separate strips. The patch may have a slot and two accompanying strips. An arrangement of multiple sensors may detect the position of an object in two or three dimensions. | 12-20-2012 |
20120319919 | PIFA ARRAY - A PIFA (Planar Inverted-F Antenna) array antenna has multiple PIFAs. The PIFA array is used to provide different radiation patterns for communication. A signal being emitted by the PIFA array is manipulated.
