    Abstract: 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.

    Abstract: A patch antenna receives circularly polarized RF signals from a satellite. The antenna includes a radiating element. A plurality of feed lines feed the radiating element at a plurality of feed points. The feed points are spaced apart to generate a circularly polarized radiation beam solely in a higher order mode at a desired frequency. The antenna may include a plurality of parasitic structures. The feed point spacing and/or the parasitic structures tilt the radiating beam away from an axis perpendicular to the radiating element. Thus, the patch antenna provides excellent RF signal reception from satellites at low elevation angles.

    Abstract: An antenna for receiving and/or transmitting radio frequency (RF) signals at multiple cellular frequency bands is disposed on a non-conductive pane. The antenna includes a first antenna element and a second antenna element. The first antenna element has a first radiating element and a second radiating element arranged together in an opposing relationship to form a first bowtie shape. The second antenna element is spaced from the first antenna element and has a third radiating element and a fourth radiating element arranged together in an opposing relationship to form a second bowtie shape with a different dimension than the first bowtie shape. A first trace element connects to and extends between said first and third radiating elements and a second trace element connects to and extends between said second and fourth radiating elements. The antenna establishes an electromagnetic coupling for dual band operation at the multiple cellular frequency bands.

    Abstract: A microwave oven with halogen lamps is disclosed. In the microwave oven, two upper halogen lamps are installed on the top wall of a cavity of the microwave oven at a position corresponding to the central portion of a turntable. Two lower halogen lamps are installed on the bottom wall of the cavity so as to be diagonally opposite to the upper lamps and to not overlap with the upper lamps. Therefore, the light, emanating from the upper and lower lamps, is uniformly transmitted to the total area on the turntable. The upper lamps are positioned to overlap with the central portion of the turntable. The lower lamps individually have an output power of lower than that of each upper lamp. The lower lamps are positioned to be radially spaced apart from the central portion of the turntable. The microwave oven of this invention thus uniformly heats and cooks food laid on the turntable while effectively preventing thermal damage of a turntable motor due to heat of the lower lamps.
