摘要： A dual-band antenna system for use in a portable communications device is disclosed herein. The antenna system includes an antenna element (10) for radiating electromagnetic energy within low-band and high-band wavelength ranges. In a preferred embodiment, a low-band isolator network (20), coupled to the antenna element (10), provides signal isolation between high-band and low-band signal paths during high-band operation. Similarly, a high-band isolator network (18) provides signal isolation, during operation over the low-band range of wavelengths, between the high-band and low-band signal paths. During transmit and receive operation, low-band and high-band electromagnetic energy directed through the antenna (10) is passed by the low-band and high-band isolator networks, (20) and (18) respectively. Also included are low-band and high-band matching networks (28) and (36), respectively, which couple the low-band and high-band isolator networks (20) and (18), respectively, to low-band and high-band transceiver circuitry.

摘要： In a multiplexer comprising two or more inputs (IN1, IN2) for connection to respective transmission sources and a common output for connection to an antenna (ANT), the inputs being connected to the output by respective filters (10, 12) tuned or tunable to separate passbands, each filter comprises at least two resonant stages (S1, S2) with both its final stage (S2) and its penultimate stage (S1) coupled to the common output. The multiplexer is arranged so that the transmission characteristic of each filter is substantially unaffected by a change in the operating frequency of the or any other channel.

摘要： Antenna sharing device used for a communications system such as a land mobile radiotelephone which has a transmitting frequency and a receiving frequency that are different from each other, and which commonly uses the antenna for transmission and reception. The bands of transmission and reception of the antenna sharing device are each divided into half and are switched into a pair of sending side low-pass filter (14) and a receiving side low-pass filter (16) and a pair of sending side high-pass filter (15) and a receiving side high-pass filter (17) by switching means (18, 19, 20), whereby the band widths of transmission and reception are narrowed and the isolation point is increased between the transmission and reception.

摘要： The coupler comprises a principal corrugated waveguide (10) and four identical secondary waveguides (11) regularly disposed on the perimeter of the principal waveguide and in such a way that the five axis are parallel. Coupling units (12) allow transfer of energy between principal and secondary waveguides. Due to reactance boundary conditions and size, only the HE11 mode in the higher frequency band and the EH11 mode in the lower frequency band can propagate in the principal waveguide. This perserves the polarization characteristics. Directional filtering is obtained by close agreement of phase constants in the different waveguides and 90 phase change between two successive coupling units in the higher frequency band, and evanescence or very low phase constant in the secondary waveguides in the low frequency band.

摘要： Bandpass filters and filter banks which use tapped planar superconductive delay lines are disclosed. Tapping is performed by backward-wave couplers which, in one embodiment, are of approximately equal length in a given channel. The low losses of superconductors make the use of tapped delay lines practical. Because tapped delay line filters are nonresonant structures, the stored energy density within the filter will be much less than that in a conventional coupled-resonator filter. This permits even a compact superconducting filter to handle large power densities like those common in telecommunications filter banks. Appropriate weighting of the taps reduces side-lobe response, and deviations from linear phase are compensated by predistortions in the tap weighting.
