    摘要: An antenna for radiating an electromagnetic field having both linear and circular polarization includes a ground plane and a dielectric layer. The dielectric layer is disposed on the ground plane and has at least one exposed surface that radiates the electromagnetic field. A first feeding element is disposed on the exposed surface for electrically exciting the dielectric layer to provide the linear polarization at a first frequency having a first effective wavelength. A second feeding element is disposed on the exposed surface for electrically exciting the dielectric layer to provide the circular polarization at a second frequency having a second effective wavelength. The feeding elements are separated by a distance greater than ⅛ wavelength of the largest of the effective wavelengths.

    摘要: A patch antenna includes a first patch element and a second patch element. Each patch element defines a center. The second patch element is spaced below the first patch element. A connection point is defined on the second patch element for connection to a transmission line. A first plane is defined through the connection point and the center of the second patch element and generally perpendicular to the second patch element. The first patch element is disposed offset the second patch element such that the center of the first patch element does not intersect with the first plane.

    摘要: The invention provides a method of operating a patch antenna having a radiating element. The radiating patch is excited and generates a circularly polarized radiation beam solely in a higher order mode at a desired frequency. This allows for the radiating element to have a small surface area with the radiating beam tilted away from an axis perpendicular to the radiating element. Thus, the patch antenna provides a relatively small footprint and excellent RF signal reception from SDARS satellites at low elevation angles.

    摘要: A patch antenna for receiving and/or transmitting circularly polarized RF signals includes a first radiating layer and a second radiating layer disposed substantially parallel to each other. Each radiating layer defines a pair of perturbation features. A ground plane layer is disposed underneath the radiating layers. The antenna also includes a feed line layer implemented as a coplanar wave guide and disposed between the radiating layers. The feed line layer allows for connection of a single transmission line to the antenna and for electromagnetically connecting the radiating layers to the transmission line. Dielectric layers separate the radiating layers, feed line layer, and ground plane layer.

    摘要: An antenna for receiving and/or transmitting circularly and linearly polarized RF signals includes a circularly polarized radiation element and a linearly polarized radiation element. The radiation elements are disposed co-planar and spaced apart from each other on a pane of glass. The linearly polarized radiation element is fed with a phase-shifted signal line. A ground plane is disposed parallel to the radiation elements to sandwich a dielectric of air. The antenna produces the effect of tilting a radiation beam from a higher to a lower elevation angle to achieve a higher gain at lower elevation angles.

    摘要: An antenna for receiving and/or transmitting circularly and/or linearly polarized RF signals includes a radiation element, a ground plane, a dielectric substrate, and a feed line. The radiation element is disposed on a pane of glass. The radiation element defines a slot having a first leg and a second leg forming the shape of a cross for generating the circular and/or linear polarization. The cross-shaped slot includes a center point. The ground plane is disposed substantially parallel to and spaced from the radiation element. The dielectric substrate is sandwiched between the radiation element and the ground plane. The feed line extends within the dielectric substrate and is electromagnetically coupled with the radiation element and the ground plane. The feed line terminates at a distal end short of the center point of the slot. That is, the feed line does not cross the center point. The antenna is compact in size and generally conformal to the pane of glass.

    摘要: An antenna (10) suitable for receiving circularly polarized RF signals from a satellite is integrated with a window (12) of a vehicle (14), such as a roof window (12). The antenna (10) includes a patch element (18) disposed adjacent to the window (12). Radiating strips (26) forming at least one dipole pair are disposed below the patch element (18) and connectable to a transmission line. A coupling element (20) surrounds the radiating strips (26) and a dielectric layer (38) is sandwiched between the patch element (18) and the radiating strips (26). A ground plane (36) is also disposed below the radiating strip (26). A conductive casing (46) perpendicularly surrounds the antenna (10) elements while electrically connecting the ground plane (36) to the coupling element (20) such that the radiating strips (26) are generally disposed within a cavity (24).

    摘要: An antenna system and method utilize a splitter electrically connectable to a single antenna for splitting an RF signal into two signals. A variable phase shifter shifts the phase of one of the signals. A combiner combines the phase shifted and non-phase shifted signals to produce a conditioned signal. A quality examiner circuit changes the amount of phase shift provided by the variable phase shifter to produce a plurality of different conditioned signals. The quality examiner circuit then determines a quality of each conditioned signal and changes the phase shift again to provide the highest quality conditioned signal to a receiver.
