INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to portable radios (e.g., operating in the ms (industrial, medical, and scientific) frequency band - having Bluetooth capability or IEEE Xie .11 capable of setting the antenna. More specifically, the present invention relates to a bipolar antenna and related method capable of being positioned at or within one of the radio housings of the portable radio unit. An L-angle antenna loop formed by a loop strip is disposed on a substrate. The loop strips extend in a first polarity direction or a second polarity direction. The second polarity direction is orthogonal to the first polarity direction. The loop strips are sized and connected to each other in an orthogonal (four) direction: resonating with the IMS or other selected frequency band. [Prior Art] Modern society _ uses a radio communication system to communicate. 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 radiocommunication k systems. The cellular k-system is an example of a radio communication system used at a high level. Honeycomb communication systems are typically constructed to provide coverage of 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 using a wireless device, a radio transceiver (sometimes referred to as a mobile station or user equipment (UE)). The access of the 1306I2.doc 1362785 cellular communication system is generally provided in accordance with the purchase of a subscription (either in a round (e.g., once a month) manner or in a prepaid, time-based manner). Honeycomb communication systems that can operate in accordance with different operational standards are defined in different frequency bands (eg, in the 8〇〇μη band, in the 9〇0 MHz band, and in positions between 丨7 (}11£ and 2 2 gHz) Radio air interface of the frequency band. Other types of radio communication systems are also widely used, for example, Bluetooth-based (tm) and IEEE 8〇2 n-based systems, which are implemented, for example, as WLAN (Wireless Area Network) systems. It generally also provides voice and data access (in a smaller coverage area than the cellular communication system). Wlan generally operates as a private network by using Bluetooth-enabled or 802.11-capable wireless devices. The ability to communicate over such networks is provided to users who can access such networks. It is configured to connect to a public network, such as the Internet, and then to other communication networks, such as PSTN. (Public switched telephone network) and PLMN (Public Mobile Network). Interworking entities are sometimes provided to provide a more direct connection between a small area network and a PLMN. The system is implemented in the 24 QHz band. Radio communication systems are generally subject to bandwidth limitations. That is, the bandwidth allocation for their operation is limited. Moreover, such limited bandwidth allocation imposes restrictions on the communication capabilities of the communication system. We have made a lot of efforts and attention in the way that high-efficiency use distribution is limited in the limited bandwidth of systems with bandwidth limitations. Sometimes bipolar communication technology is used. In a bipolar technology, it is transmitted at the same frequency. The data is conveyed in a separate polar plane. By using bipolar technology, the communication capability can be nearly doubled. To convert the signal energy according to a bipolar scheme, the wireless skirt needs to use a polar plane that can be separated at 130612.doc 1362785. One of the bipolar antennas in operation. The advantage of using bipolar technology is that it generally reduces the effects of multipath transmission and other interference, thereby improving the quality of signal transmission and reception. Bipolar antennas can be fed by an edge Or a probe feed is implemented by feeding a square patch antenna at its two orthogonal edges. 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 individual feed lines from occurring. Coupling between. Excessive amount of coupling results in higher cross-polarity levels. Since wireless devices have an increasingly larger size, they are packaged in smaller and smaller housings. Related problems may become more and more obvious. It is necessary to construct a modified bipolar antenna in one way to reduce such harmful problems. The present invention has been made in view of this prior art information related to antennas for radios. The obvious improvement was developed. [Summary of the Invention]

And the operating standard by which the network station can operate is licensed for bipolar communication in the operating band of the communication system (here extending between -4 and 2 485 GHz) and thus provides Bipolar pass 130612.doc. The mobile station 2 includes a transceiver circuit, here denoted as - receive (four) part 26 and - transmit (TX) (four) 28. The receiving and transmitting part is (for example) by -day (four) The combiner or other entity that provides isolation between the transceiver portions in accordance with the embodiment of the present invention - the antenna 32 is capable of bipolar operation. gp, the transmission and reception Part can be generated for the two polar directions The signal transmitted on and also operates on signals transmitted to the mobile station in the two polar directions.

Due to the substantially vertical intersection of the adjacent loop strips, the loop strips each extend in one of two polar directions. The polar directions are orthogonal and are defined by axes 72 and 74. The axis 74 defines a first polarity direction, and the pumping 72 defines a second polarity square extending between reference points, > between test sites 6G and 58, between reference points 62 and 68, and reference points & The loop strips between % extend in the direction of the first polarity.
