    Abstract: PROBLEM TO BE SOLVED: To provide a cable which has approximate RF invisibility in an RF band of interest, having a flexibility and can be used in a variety of test forms.
    SOLUTION: A flexible test cable has a center conductor (210), a conductive sleeve (240) with an effective electrical length equal to an odd quarter wavelength of a frequency of interest, a dielectric spacer (230) located inside the conductive sleeve (240) for preventing a portion of the center conductor (210) from electrically coupling to the conductive sleeve (240), and a dielectric joint (220) for maintaining a portion of the center conductor (210) in the middle of an end of the conductive sleeve (240). The dielectric spacer (230) can be formed in a variety of shapes from rigid or compressible dielectric materials. Using the dielectric joint (220) to link together multiple conductive sleeves (240) results in a flexible test cable (200) with electrical transparency at the frequency of interest.

    Abstract: A radio receiver, and associated method therefor, for generating a baseband sign al having signal component portions of time-varying frequencies. The oscillating signal generated by at least one of th e low oscillators of down-mixing circuitry (680, 744, 750) of the receiver is modulated by a low-frequency signal thereby to cause the resultant, baseband signal to be comprised of signal component portions of time-varying frequencies. Because the signal component por tions of the baseband signal are of time-varying frequencies, attenuation of such signal component portions and resultant distort ion of the received signal, as a result of undesired notches in the frequency response of a radio receiver is avoided.

    Abstract: An antenna arrangement (402) for a wireless communication device (400) comprises a first element (404) and a second element (406). The first element (404) is coupled to circuitry (408) of the wireless communication device (400). The second element (406) is movable between a first and a second position relative to the first element (404). The performance of the antenna arrangement (402) is substantially less desirable when the second element (406) is between the first and the second position than the performance of the antenna arrangement (402) when the second element (406) is at either the first or the second position. The second element (406) is mechanically spaced apart from and substantially electrically coupled to the first element (404) in both the first and the second position. The antenna arrangement (402) advantageously provides for reduced dimensions while achieving desirable performance.

    Abstract: An antenna assembly (100), and associated method, for a radio, such as a portable radiotelephone, which is of minimal physical dimensions and which is operable over a wide range of frequencies. A length of wire (106) is helically-shaped and includes at least a portion of winding. A capacitive top-hat (136) is positioned at an end portion of the wire. By increasing the number of windings of the wire (106), the height of the antenna assembly is reduced, but such reduction also reduces the size of the bandwidth of frequencies over which the antenna assembly is operable. Increase in the size of the surface area of the capacitive top-hat (136) increases the size of the bandwidth over which the assembly is operable. Selection of the top-hat size and the number of windings permits both physical dimensions of the antenna assembly and the size of the bandwidth to be selected.
