摘要： A Planar Inverted F Antenna (PIFA) is disclosed comprising a radiating element and a ground plane positioned on a bottom cover. A Radome is positioned over the radiating element and the ground plane with the bottom cover and the Radome enclosing the radiating element and the ground plane. The ground plane is positioned below the radiating element and a conductive shorting strip extends between one end of the radiating element and one end of the ground plane. A feed lead extends from one side of the radiating element and has a base portion which protrudes outwardly of the Radome for connection to the center conductor of a RF power feeding cable. The radiating element includes a first horizontally disposed portion, a second horizontally disposed portion, and a substantially vertically disposed portion extending therebetween. The first substantially vertically disposed portion of the radiating element functions as a first capacitive loading plate with the second horizontally disposed portion of the radiating element functioning as a second capacitive loading plate. A dielectric block is positioned between the second horizontally disposed portion of the radiating element for providing dielectric loading to the radiating element.

摘要： The present invention relates to a non-rectangular shaped PIFA capable of dual ISM band operation using a single power feed. The dual frequency operation of the PIFA is accomplished by using a slot in the radiating element to quasi partition the radiating element. The dual band performance of the PIFA is realized through the integration of either the microstrip or the Co Planar Waveguide (CPW) feed line to the antenna structure.

摘要： A diversity antenna comprising two planar inverted F antennas (PIFAs) characterized by: two radiating elements with or without the physical separation between them; the spatially separable radiating elements of the two PIFAs with side-by-side or orthogonal placement with respect to each other are combined to form an equivalent single element consisting of the composite assembly of two radiators; a small ground plane of rectangular or L-shape with or without bending at its opposite ends is common to both the radiating elements; the radiating elements are placed above the unbent common ground plane; the radiating elements are placed above the vertical sections of the bent common ground plane; the shorted ends of the spatially separated radiating elements are placed back to back on the said common ground plane; a common shorting post placed along the common boundary line resulted by the merging of the two radiators with a prior side by side mutual placement; a common shorting post placed within the common boundary surface resulted by the merging of the two radiators with a prior mutual orthogonal orientation.

摘要： A Planar Inverted F Antenna (PIFA) is disclosed comprising a radiator assembly positioned in the interior of a lower Radome member. An upper Radome member is placed over the radiator assembly with the upper Radome member and the lower Radome member fully enclosing the radiator assembly. The radiator assembly is held to the upper and lower Radome members by means of three dielectric blocks on each member. The radiator assembly comprises: (1) two radiating elements placed on the opposite sides of common ground plane; (2) two separate shorting strips extending between one end of each radiating element and one end of common ground plane; (3) a common feed conductor in the form of a single strip connecting one edge of each radiating element and the common feed conductor which has a disc-shaped portion with an opening formed therein. A ground tab is formed as an extension of the common ground plane. A hollow cylindrical structure formed as an outward extension of the lower Radome member constitutes the embedded (built-in) connector for the PIFA. A metal rod is inserted through the opening in the disc-shaped portion and protrudes into the hollow cylindrical structure to serve as the feed (center) pin of the embedded connector. A cylindrical dielectric block on the bottom surface of the upper Radome member holds the feed (center) pin in the designed location of the embedded connector. The ground tab protrudes into the hollow cylindrical structure and maintains a flush contact with the side wall of the hollow cylindrical structure to provide the ground potential of the embedded connector.

摘要： This invention presents new and alternative design techniques of single feed Dual/Tri ISM band PIFA for wireless system applications. To attain the advantages of and in accordance with the purpose of the present invention, dual and/or tri ISM band PIFA antennas are provided. In particular, an antenna comprises at least a ground plane, a radiating element, a short, and a feed tab. The short provides a connection between the ground plane and the radiating element. The feed tab connected to the radiating element provides RF power and provides initial impedance match. While the feed tab provides initial impedance match, additional impedance match and frequency control are obtained by the inclusion of one or more of a parasitic element, a slot, tuning stubs, and capacitive elements.
