Abstract:

An integrated diversity antenna solution is presented that positions multiple antennas within the digital device case. The integrated diversity antenna solution works equally well with diversity radios, such as 802. 11, and non-diversity radios, such as Bluetooth. The non-diversity radios are supported via a power splitter attached to the antennas that give the necessary directional coverage. The integrated antenna array solves the main problem associated with wireless communication on laptop computers, specifically, that laptops perturb the radiation pattern because of the influence that laptop components have on standard antennas and the presence of interfering objects, most notably the laptop user, in the surrounding environment.

International Classification:

H04B 138

US Classification:

4555757, 343702

Abstract:

An apparatus and system for providing wireless communication for a portable computer system. In one embodiment, the present invention is a wireless communication apparatus. The wireless communication apparatus is adapted to be communicatively coupled to a portable computer system. In the present embodiment, the apparatus is comprised of a PCB (printed circuit board). It is noted that the PCB of the present invention is separate from and in addition to the PCB of the portable computer system to which it is coupled. The apparatus is further comprised of an antenna, coupled to the PCB adapted to transceive a specific radio frequency band. The apparatus is further comprised of a passive radiator coupled to the PCB. The passive radiator is adapted to provide an omindirectional radiation pattern for the wireless communication apparatus.

International Classification:

H04B 1707

US Classification:

375149

Abstract:

Synchronized receiver circuitry and methods are provided for a spread-spectrum communications system which includes a transmitter for generating a data-modulated carrier signal encoded with a predetermined discrete-stepped, cyclical pseudo-random noise code sequence, and a receiver for despreading and demodulating the encoded spread-spectrum modulated carrier signal. The receiver has a pseudo-random noise code generator, a mixer connected to the pseudo-random noise code generator for mixing the encoded spread-spectrum modulated carrier signal with the code sequence provided by the pseudo/random noise code generator to despread the carrier signal, and an indicator in the receiver for generating a received signal strength indicator analog signal. The synchronized receiver includes a clock which provides a frequency output corresponding to the frequency of the clock driving the pseudo-random noise code generator in the transmitter. The synchronized receiver also has an analog-to-digital converter for converting the analog signal to a digital signal indicative of the best correlation between the frequency and PN phase of the transmitted modulated carrier signal and the received modulated carrier signal.

David Andrus - Provo UT

Assignee:

3Com Corp. - Santa Clara CA

International Classification:

H01Q 148

US Classification:

343846

Abstract:

The present invention relates to a compact antenna for use with small, wireless, electronic devices. The antenna is particularly suited for adaptation to thin profile expansion cards such as the PC Card standard card as well as other thin form factor devices. This antenna comprises a ground plane element from which a radiator element protrudes. When the ground plane element occupies a substantially horizontal plane, the radiator element extends upwardly from a centralized location on the ground plane element and bends away from the device in which the antenna is used. The radiator may then bend back to a more vertical orientation in some embodiments. The shape of the radiator element allows the antenna to be retracted into a host device while minimizing the amount of space required to house the antenna in the device. Particular embodiments of the present invention comprise hinging mechanisms to make the antenna more compact and switching mechanisms for automatic activation of wireless functionality when the antenna is deployed.
