INSTRUCTIONS: [Technical field to which the invention pertains] 'The present invention generally relates to a band for operation in a portable radio device (e.g., in the industrial, medical, and scientific) band with Bluetooth capability or IEEE 802.U Antenna of b/g capable device). More specifically, the present invention relates to a bipolar antenna and related method capable of being positioned outside or inside a radio of one of the portable radios. A corner positioning type patch array is disposed on the substrate. The isometric positioning type η patch, together with the connecting strip interconnecting adjacent patches, is symmetrical in both the first and second polarity directions and is sized to permit symmetric excitation at a resonant frequency. [Prior Art] Radio communication systems are often used in modern society for communication. Many variations of communication services (both voice communication services and data communication services) are typically implemented by radio communication systems. Moreover, technological advances have made it possible to increase the types of communication services that can be implemented by radio communication systems. The cellular overnight system is an example of a radio communication system with high-level use. Honeycomb communication systems are typically constructed to provide coverage for a wider area. And its infrastructure is already installed in an important part of the global residential area. The user communicates via a radio communication system through the use of a wireless device, a radio transceiver (sometimes referred to as a mobile station or user equipment (UE)). Access to a cellular communication system is typically provided in accordance with a subscription (taken one cycle (i.e., once a month) or a prepaid, time-based) purchase. Honeycomb communication systems that can be operated according to different operating standards are defined in different frequency bands (for example, in the band of Iona J10.doc 200901560, in the 900 MHz band, and in the band between i_7 GHz and 2.2 GHz) Radio air interface. Other types of radio communication systems are also widely used, for example, Bluetooth-based (tm) and IEEE 802.11 b/g-based systems, which are implemented, for example, as WLAN (Wireless Local Area Network) systems, which generally provide voice and Data pass k (in a smaller coverage area than the cellular communication system). Wlan — operates as a private network that provides the ability to communicate over such networks by using Bluetooth-enabled or 802·11 b/g capable wireless devices. Use 纟. WLANs are sometimes configured to connect to a public network, such as the Internet, and in turn to a proprietary communication network such as PSTN (Public Switched Telephone Network) and pLMN (Common Mobile Network). Interactive health entities are sometimes provided to provide a more direct connection between a small area network and a local network. The various systems described above are implemented in the 2.4 GHz band. Radio communication systems are generally limited by bandwidth. That is, for the frequency of its operation

The signal can be converted by using the (4-) 枓 system in a separate polar plane to transmit a bipolar scheme; For the separation of the polar planes in the & ^ & wireless device needs to be used, it is also beneficial, because the = ❹ bipolar technology will reduce the impact of multipath transmission and other interference 130613.doc 200901560, Thereby improving the quality of signal transmission and reception. A bipolar f-antenna can be implemented by feeding a square patch antenna at its two orthogonal edges by edge feeding or - detecting feed. In general, existing bipolar patch antennas are used in conjunction with two feed network circuits. Such existing antennas have problems due to various limitations. For example, the separation distance between the feed connections needs to be large enough to prevent the occurrence of facets between the individual feed lines. Excessive amounts of coupling result in higher cross-polarity levels. As wireless devices are available in smaller and smaller sizes and are packaged in smaller and smaller sized enclosures, the problems associated with such cross-polarity levels may become more pronounced. An improved bipolar antenna that needs to be constructed in one way to reduce such deleterious problems. In view of the prior art information with antennas for radios, significant improvements in the present invention have been developed. SUMMARY OF THE INVENTION Accordingly, the present invention advantageously provides a portable radio device (e.g., one that is compatible with Bluetooth or compatible with 802.11 b/g in IMS (Industrial, Medical, and Scientific) band operation) Antenna equipment and related methods. A bipolar antenna having a compact configuration is provided by the operation of one embodiment of the present invention. The antenna can be positioned at or within one of the radio housings of the portable radio. In one aspect of the invention, the antenna is formed by an array of angularly positioned patches disposed on the substrate. The isometric positioning type patch is symmetrical with both the first polarity direction and the second polarity direction of the adjacent strips. Moreover, the conductive material remaining or otherwise disposed on the substrate can be symmetrically excited at one of the IMS frequency bands (e.g., 3130613.doc 200901560 2.47 GHZ). In another aspect of the invention, the isometric positioning patch forms an array of patches, wherein each patch of the array is of a corresponding geometric dimension. Each patch is, for example, square. Each square patch has a common longitudinal and lateral dimension 'to allow the resulting array to be in two directions (a first polarity direction and a - polarity direction) where the second polarity direction is aligned with the first polarity direction ) is symmetrical. The patches are formed, for example, at the corners of a rectangular substrate such that the patches extend to the edge side of the substrate. In another aspect of the invention, a strap is disposed on the substrate to interconnect adjacent patches in the patch of the array. Since the patches are configured as -2X2 arrays, four tie strips are used, and #一连接带 will be connected to the adjacent strips. - When the strap extends m, or in a second polarity direction, which pair of patches in the array are interconnected by the straps. The straps are positioned to provide a symmetry through one of the channels extending in the same direction as the polarity in which the straps extend. When positioned adjacent to the adjacent patch of the 2x2 array, the two straps of the four straps extend in the first polarity direction and are axisymmetric with respect to one of the polarities extending in the first polarity direction. And a second pair of connecting strips of the four connecting strips extend in a second polarity direction and are symmetric with respect to a polarity axis extending in a direction of a second polarity. The straps thus interconnect each adjacent patch of the array and generally interconnect all of the patches of the array. In another aspect of the invention, the towel is placed on the substrate and 130613.doc
