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: 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: A multi-band antenna comprising a device which is capable of functioning during at least a lower frequency band of operation and at least a higher frequency band of operation. The antenna comprises an elongated radiating element having a helical radiating element connected to one end thereof with one end of the helical radiating element being received by a non-conductive insulator. An outer conductive shell embraces the non-conductive insulator and at least partially encloses a portion of the helical radiating element. The straight radiating element acts as the antenna radiator during both the high and low frequency bands of operation.

摘要: An antenna is provided for a wireless communication device such as a handheld radio or cellular telephone. The antenna may be either embedded internally in the transceiver or may be mounted externally thereof. The antenna comprises a pair of 1/4 wave radiating elements which are coupled out of phase to create an end fire bi-directional pattern for the antenna. The radiating elements are attached to a micro-strip transmission phasing device which is comprised of a center conductor, a ground plane and a substrate material. The micro-strip transmission phasing device supplies a zero degree to one hundred eighty degree phase shift from one radiating element to the other radiating element.

摘要: A PCMCIA antenna for wireless communications is provided which provides the performance of a 1/2 wave antenna used for wireless communication, both transmission and receiving, on PCMCIA and other platforms for wireless data communications. The antenna comprises a housing which is adapted to be secured and supported by the host device and comprises a housing including housing members which are ultrasonically welded together. A flexible circuit board is provided in the housing which serves as the lower radiating element. A coaxial cable extends into the housing and has its braid soldered to the lower radiating element so that the same serves as a counterpoise for the antenna. The center wire of the coaxial cable is connected by a flexible trace to a flexible printed circuit board which is encased in an insulated sheath which forms the upper radiating element. The upper radiating element is pivotally secured to the housing so that the upper radiating element may be moved to a stowed position wherein it is parallel to the longitudinal axis of the housing, where it may be pivotally moved upwardly with respect to the housing to a 90 degree angle with respect to the housing.
