Title: Dual feel multi-band planar antenna

Abstract: A three-band, two-antenna, assembly includes a planar inverted-F antenna (PIFA) having a radiating/receiving element that is spaced from and extends generally parallel to a ground plane element. The planar radiating/receiving element of an inverted-F antenna (IFA) is located in an open space that exists between the radiating/receiving element of the PIFA and the ground plane element. The radiating/receiving element of the IFA extends either perpendicular to, or parallel to, the radiating/receiving element of the PIFA. The radiating/receiving element of the PIFA includes one or more open slot configurations that operate to provide dual resonant frequencies for the IPFA (AMPS/PCS or GSM/DCS). The radiating/receiving element of the IFA operates in a non-cellular frequency band (ISM or GPS).
