摘要： A slot antenna for short-range communications between wireless communication devices is described herein. The antenna comprises a radiating plate spaced from a ground plate. A slot in the radiating plate defines the resonant frequency of the antenna. A spiral feed element disposed beneath the slot and between the ground plate and the radiating plate feeds transmission signals to the antenna. The slot antenna may be used in any portable wireless communication device configured to transmit short-range wireless signals, such as Bluetooth® signals.

摘要： In one embodiment, a method for balancing clock signals in a clock tree includes, at a register, receiving a divided input clock signal and a non-divided input clock signal and generating a first output clock signal based on the received divided input clock signal and the received non-divided input clock signal, the first output signal being associated with a first delay. The method further includes, at a delay line, receiving the non-divided input signal, delaying the non-divided input signal for a time substantially equivalent to the first delay, and generating a second output clock signal associated with a second delay substantially equal to the first delay. The method further includes: (1) receiving at a multiplexer the first output signal, the second output signal, and a select control signal indicating which of the first output signal or the second output signal to select; (2) selecting at the multiplexer either the received first output signal or the second output signal based on the select control signal; and (3) generating the selected first output signal or second output signal as a substantially balanced third output signal.

摘要： An antenna system includes a planar substrate, a conductive ground plane, and an upper antenna element. The conductive ground plane is on the substrate. A slot that is free of conductive material extends through the ground plane to define a lower antenna element from a portion of the ground plane. The upper antenna element is spaced apart and overlies at least a portion of the lower antenna element. A first location of the upper antenna element is electrically connected to the ground plane and a spaced apart second location of the upper antenna element is electrically connected to an antenna feed element. The upper antenna element is configured to electrically resonate responsive to a defined RF signal. The lower antenna element is configured to resonate through capacitive coupling to the resonating upper antenna element.

摘要： An antenna that includes an ultra wideband (UWB) feed element, a parasitic conductive element, and a radio frequency (RF) switch. The UWB feed element is capable of radiating a first frequency band. The parasitic conductive element is connected to an electrical ground and capable of radiating a second frequency band. The parasitic conductive element has no electrical contact with the UWB feed element. The RF switch is connected between the parasitic conductive element and the electrical ground and configured to vary an electrical current path between the parasitic conductive element and the electrical ground. The varying of the electrical current path changes a resonant frequency of the second frequency band of the antenna.

摘要： An antenna configuration for a flip type mobile phone is disclosed. The antenna configuration is designed to reduce, to a hearing aid compatibility (HAC) M3 rating or better, any scattered EM field effects that can cause interference to an active hearing aid. The antenna configuration comprises a halfwave type antenna extendable from the lower portion of the mobile phone. The antenna does not share the same vertical axis as the lower portion of the mobile phone when extended. Rather, it forms a tilt angle (α) that extends the antenna away from the upper portion of the mobile phone creating a greater separation distance between the speaker and the antenna. An antenna feed contact couples the antenna to components within the mobile phone. An antenna matching network can tune and attenuate the antenna configuration to enhance operation in the GSM frequency bands.
摘要翻译：公开了一种用于翻盖式移动电话的天线配置。天线配置旨在降低助听器兼容性（HAC）等级或更好的任何散射的EM场效应，从而可能对主动助听器造成干扰。天线配置包括可从移动电话的下部延伸的半波型天线。当延伸时，天线不能与手机的下部共享垂直轴。相反，它形成了将天线延伸远离移动电话的上部的倾斜角（α），从而在扬声器和天线之间产生更大的间隔距离。天线馈电触点将天线耦合到移动电话内的组件。天线匹配网络可以调谐和衰减天线配置，以增强GSM频段的操作。

摘要： The Lopsided Payload Carriage Gimbal in al its embodiments allow Aerial Vehicles and Water-borne vehicles to carry payloads far from the vehicle Geometric Center without significant travel of the vehicle's overall Center of Gravity. Large travel of the CG limits vehicle's performance or renders it inoperable. The embodiments rely on the interaction of the payload and the counter balancing weight through the payload link 18, balancing link 10 main link 14 and battery pylon 8 to substantially reduce the torque generated by the payload in a lopsided position. The embodiments also allow the vehicle carrying the payload to change thrust direction agilely. Finally, the embodiment acts as a mechanical stabilization device for the payload as well. This invention is adaptable to all forms of hover-capable aerial vehicles as well as water-borne vehicles.

摘要： An improved low profile antenna of the PIPA PIFA style is formed from a single piece of useful conductive material and includes a first plate spaced apart from an elongated ground plate. The first and ground plates are interconnected by a shorting plate having a width less than that of either the first or ground plate. A feed plate is interposed between the two plates and is either completely covered by the first plate or slightly exposed. Such antennas have extremely large bandwidth of up to about 50%.
