Abstract
A dual feed internal antenna is disclosed which provides an internal antenna with multiple frequency response through the use of two or more internal antennas within one package. Each internal antenna has its own feed and ground connection. For example, a planar inverted F antenna provides response at cellular telephone frequencies and an inverted F antenna provides response at Industrial, Scientific, and Medical (ISM) band of frequencies.
