Embodiment Construction

[0027] Therefore, first refer to figure 1 A wireless communication system, generally indicated at 10 , provides communication with mobile stations 12 . In this example embodiment, the mobile station operates according to the Bluetooth standard or the IEEE 802.11b / g standard, and can transmit and receive signals on the 2.4 GHz frequency band. More generally, the mobile station 12 represents any of a variety of wireless devices, and the wireless communication system represents any of a variety of wireless communication systems that may operate in accordance with any of a variety of communication standards or allow operation on unregulated frequency bands. A wireless communication system. Therefore, while the following describes examples of Bluetooth or IEEE802.11b / g compatible systems operating in the 2.4GHz frequency band, it should be understood that the following descriptions are exemplary only and that descriptions of the operation of wireless communication systems operatin...

Abstract

A dual-polarized antenna, and an associated methodology, is provided for a radio device, such as a mobile station. The antenna is formed of a plurality of patches configured into an array, symmetrical in both a first polarization direction and a second polarization direction. Adjacent patches of the array are interconnected by connecting strips that are also symmetrically positioned in the two directions. These connecting strips not only act as feeding lines for the patches but also operate as in-phase radiation elements in each polarization direction. A transverse strip extends between a pair of transversely positioned patches. And a single feed connection is provided thereat.

Description

technical field [0001] The present invention generally relates to antennas for portable wireless devices, such as Bluetooth or IEEE802.11b / g enabled devices operating in the IMS (Industrial, Medical and Scientific) frequency band. More particularly, the present invention relates to a dual-polarized antenna with a compact structure that can be located on or within a wireless housing of a portable wireless device, and related methods. [0002] An array of patches located at the corners is arranged on the substrate. The corner patches and the connecting strips interconnecting adjacent patches are symmetrical in the first and second polarization directions and have dimensions that allow symmetrical excitation at the resonant frequency. Background technique [0003] Wireless communication systems are used in many aspects of modern society to communicate. Many different communication services, including voice communication services and data communication services, can be regular...
