Abstract: A bent-segment helical antenna utilizes one or more radiators wrapped in a helical fashion. The radiators are comprised of a plurality of segments. A first segment extends from a feed network at a first end of a radiator portion of the antenna toward a second end of the radiator portion. A second segment is adjacent to and offset from the first segment. A third segment connects the first and second segments at the second end of the radiator portion.

Abstract: A dual-band coupled-segment helical antenna provides operation in two frequency bands. The dual-band coupled-segment helical antenna includes a radiator portion having two sets of one or more helically wound radiators extending from one end of the radiator portion to the other end of the radiator portion. Radiators of the first set of radiators are comprised of two segments: a first radiator segment extends in a helical fashion from one end of the radiator portion toward the other end of the radiator portion; and a second radiator segment is U-shaped and extends in a helical fashion from the first end of the radiator portion toward the second end of the radiator portion. Radiators of the second set of radiators are comprised of a radiator disposed within said U-shaped segment. The first set of radiators resonates at a first frequency and the second set of radiators resonates at a second frequency thereby providing dual-band operation, with minimal coupling between the frequency bands.

Abstract: Transmitter architectures for a communications system having improved performance over conventional transmitter architectures. The improvements include a combination of the following: faster response time for the control signals, improved linearity, reduced interference, reduced power consumption, lower circuit complexity, and lower costs. For a cellular application, these improvements can lead to increased system capacity, smaller telephone size, increased talk and standby times, and greater acceptance of the product. Circuitry is provided to speed up the response time of a control signal. The control loop for various elements in the transmit signal path are integrated. A gain control mechanism allows for accurate adjustment of the output transmit power level. Control mechanisms are provided to power down the power amplifier, or th e entire transmit signal path, when not needed. The gains of the various elements in the transmit signal path are controlled to reduce transients in the output transmit power, and to also ensure that transients are downward.

Abstract: A method of manufacturing a helical antenna having a substrate (406), the method comprising providing a series of holes (2230) in the substrate (406) and positioning the substrate (406) to engage a support element (2310). The support element (2310) has a series of teeth (2312) adapted to mate with the holes and extending radially outward from an outer surface of the support element. The teeth are arranged so that on rotation of the support element (2310) about its major axis, the substrate (406) is wrapped around the support element (2310). In preferred embodiments, the teeth (2312) and holes (2230) are arranged such that prior to rotation of the support element (2310), at least one of the teeth (2312) mates with a corresponding at least one of the holes (2230) and upon rotation, at least one additional tooth (2312) mates with a corresponding at least one additional hole (2230).

Abstract: A dual-band coupled-segment helical antenna is provided operating in two frequency bands. The dual-band coupled-segment helical antenna (1200) includes a radiator portion (1202) having two sets of one or more helically wound radiators (1204, 1212) extending from one end (1234) of the radiator portion {1202) to the other end (1232) of the radiator portion (1202). Radiators of the firs set of radiators ( 1204) are comprised of two segments: a first radiator segment (1208) extends in a helical fashion from one end of the radiator portion (1202) toward the other end of the radiator portion (1202); and a second radiator segment (1210) is U-shaped and extends in a helical fashion from the first end of the radiator portion (1202) toward the second end of the radiator portion (1202). Radiators of the second set of radiators (1212) are comprised of a radiator (1212) disposed within said U-shaped segment (1210). The first set of radiators (1204) resonates at a first frequency and the second set of radiators (1212) resonates at a second frequency thereby providing dual-band operation, with minimal coupling between the frequency bands.
