    Abstract: A novel and improved antenna adapter for interfacing a portable radiotelephone (200) with test equipment is disclosed. In a preferred embodiment, the adapter assembly comprises an RF connector (104) at one end of an elongated conductor (102) which connects directly to the radiotelephone's (200) antenna port, replacing the normal antenna assembly. The elongated conductor (102) makes electrical contact with an external ground (204) of the battery charging ports at the bottom of the radiotelephone (200) at another end. The RF connector (104) may be impedance-matched to minimize RF signal attenuation when connected to the RF test equipment. In an exemplary embodiment, the RF connector (104) comprises a 50 OMEGA impedance-matched SMA connector.

    Abstract: An antenna adapter (100) for interfacing a portable radiotelephone (200) with external equipment. In a preferred embodiment, a connector assembly (404) includes a first connector portion (406) that inserts directly into the radiotelephone's antenna port, replacing the normal antenna assembly. Matching electrical components (410) on a circuit board (400) are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion (408) typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.

    Abstract: A novel and improved antenna coupler (100) useful in an adapter for a portable radiotelephone (200). In a first embodiment, a plurality of curved bands (204a-204c) of metal are positioned on a ground plane (102), with at least one of the plurality of curved bands of metal (204a-204c) being electrically isolated from the ground plane (102) so as to couple RF signals to and from the antenna (204) of a portable telephone (200). At least one ground pin (206a, 206b, 206c) is also mounted on the ground plane (102). When a portable radiotelephone (200) is interfaced with the antenna coupler (100), the at least one ground pin (206a, 206b, 206c) makes electrical contact with assembly screws (202a, 202b) or an external ground pad (208) of a battery charging port on the portable radiotelephone (200). In a second embodiment, a coupling pin (404) makes direct contact with a component of the RF chain of the portable radiotelephone (200). In a third embodiment, a helical coupler (504) surrounds the antenna (204) of the portable radiotelephone (200).

    Abstract: A novel and improved dual band antenna system comprising an inner antenna element surrounded by an outer antenna element. In a first embodiment, the inner antenna element radiates and receives RF signals in a first RF band, and the outer antenna element radiates and receives RF signals in a second RF band. Optionally, the inner and outer antennas may be coupled together when operating in the first RF band in order to improve the antenna gain pattern of the dual band antenna. In a second embodiment, the inner antenna element radiates and receives RF signals in both the first and second RF bands. In this second embodiment, when operating in the second RF band, the outer antenna element is grounded, thus altering the signal length of the inner antenna element to resonate in the second RF band.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to determine whether to maintain or remove a radio frequency (RF) path from a set of candidate paths considered for transmit antenna switch diversity (ASDIV). The determination allows the UE to avoid signal loss or degradation in coexisting networks at similar frequency ranges. For example, ASDIV allows two or more antennas to form different input and output ports to establish different RF paths. Coexistent networks, such as wireless wide-area-network (WWAN) and wireless local- area-network (WLAN) may utilize different RF paths to optimize reliability and efficiency. The overlapping of the bands may cause signal attenuation or degradation from at least one of the networks. The present disclosure provides techniques for detecting signal attenuation at least partially caused by overlapping bands and removing an associated RF path to avoid such signal loss or attenuation.
