The pifa generally has a compact size, a low profile, and a dual band (4). _, this type of antenna structure generally exhibits a narrow bandwidth. In order to enhance the bandwidth of a PIFA, sometimes the structure of the PIFA is combined with a parasitic element or a multi-layer three-dimensional structure: however, such addition increases the size of the antenna ^ In addition, due to the additional resonant branch As a result, tuning of the antenna becomes difficult. Moreover, these branches sometimes introduce EMC and EMI, which interfere with the conversion of signal energy. Therefore, it is desirable to use a modified antenna structure that is small in size and allows for use in multiple frequency bands. The present invention has been substantially improved in accordance with this and the background information for antenna converters for radio devices. SUMMARY OF THE INVENTION Accordingly, the present invention advantageously provides an antenna device and a related method for a mobile station or other radio device that can operate over multiple frequency bands. Through the operation of one embodiment of the present invention, a method is provided by which a multi-mode turret or other radio device that can operate, for example, in (four)...卯...in the (eight)/...(9)訄^^ band, A hybrid strip antenna. In one aspect of the invention, an antenna system is formed by first and second radiating elements including a loop and a strip. The radiating element is configured to be 129970.doc 200901556 corresponding to the radio device being resonable at the frequency of the frequency band in which it operates. In the 'pattern', the substrate is provided with a size that allows it to be in the base of the housing of his compact size radio: the substrate has a rectangular or other geometric configuration and allows a conductive material = upper Printing or other applications. The size of the substrate is large enough to allow the formation of a "conductive loop." The loop has a length on the substrate that can be formed on the substrate, the band, and the length of the vibration. The loop is formed around the periphery of the substrate (e.g., extending $2, Ai to the peripheral edge). The loop formed around the periphery of the substrate is provided with a feed-and-contact (four) connection. The length is 1 帛-resonant frequency band. That is, the length of the loop resonates in a first frequency band. The length of the loop is selected by the appropriate number, and the loop is at least the operating mode corresponding to the operating mode of the mobile station. Resonance at the frequency band. In the state of the present month, the circuit extending around the periphery of the substrate includes a curved line; an IL line. The meander line is, for example, tied to the substrate formed by the circuit. One of the surrounding is formed. The streamline has a length that resonates at a second frequency band. The second frequency band of the meander line in its resonance is determined by its length. However, by appropriately selecting the length of the meander line, the meandering of the loop is caused. The line portion resonates at (4) a frequency band of an operating band of one of the multimode mobile stations. The meandering line is formed, for example, by forming a non-conducting segment (ie, a 'finger) with a loop formed around the periphery of the substrate. A rectangular strip of one of the conductive materials is formed by a fork. The length of the meander line is increased by increasing the recombination of the non-conductive segments or fingers. A suitable resonant frequency is used by using - 129970.doc 200901556 Therefore, a loop formed around the periphery of the substrate and including a meandering stream as its one knife defines a set of resonant frequency bands, the first resonant frequency band of which includes the meandering The entire length of the loop of the length of the line is defined, and its second resonant frequency band is defined by the length of the meander line. In another aspect of the invention, an L-shaped strip is also formed on the substrate. The L-shaped belt system Formed in an inner region defined by a loop extending around a periphery of the substrate. One end of the L-shaped strip is electrically coupled to the peripheral loop. The L-shaped strip is, for example, shorter by the L-shaped strip One end side of the side is consumed to the peripheral loop. The L-shaped strip resonates at the resonant frequency band. The resonant frequency band of the L-shaped band at its resonance depends on the length of the strip. By appropriately selecting the length of the strip, the strip The resonant frequency band of its resonance corresponds to an operating band of one of the mobile stations that picks up the antenna. In the κ yoke scheme, the antenna is used for operation in the 800/900/1800/1900 MHz band—multi-band cellular operation The configuration of the peripheral loop and the L-shaped strip is selected to cause resonance at a frequency that covers the frequency band in which the mobile station can operate. The length of the peripheral loop defines a lower frequency band and the meandering line The length of the L-shaped band resonates at a higher frequency band. The meander line and the higher frequency band of the L-shaped band resonate at a higher frequency band. The higher frequency bands of the meander line and the L-shaped band overlap or accumulate with each other to correspond to a higher operating frequency of the mobile station. Due to its compact size, operational stability and the stable 5-ray pattern provided by the antenna, the antenna is advantageously used in small size mobile stations or other radios. In this and other aspects, a hybrid 129970.doc 200901556 strip antenna and a related method are provided for a communication device. The hybrid strip antenna is embodied on a substrate. The first radiating element is formed by a loop. The loop is configured to cause the first radiating element to resonate within a first set of frequency bands. The second radiating 7L member is formed by an L-shaped strip that is coupled to and extends beyond the loop forming the first radiating element. The £-belt is configured to cause the second radiating element to resonate within a second set of frequency bands. [Embodiment] Therefore, first referring to the figure, a radio communication system (generally shown at 10) provides a mobile station for radio communication, which is represented by the mobile station 12. Here, the mobile station 12 represents a quadruple mode mobile station capable of communicating at the 800/900/1800/1900 MHz band. This mobile station is sometimes referred to as a world band mobile station because the mobile station can operate in accordance with the operational specifications and protocols of the currently dominant cellular communication system. More generally, the mobile station represents various radios that can operate over multiple frequency bands or over a relatively large frequency of relatively high frequencies. The radio access networks 14, 16, 18 and 22 represent four radio networks that are operable at the 800, 900 '1800 and 1900 MHz bands, respectively. When the mobile station 12 is positioned within the coverage area of any of the radio access networks 14-22, the mobile station can communicate therewith. If the separate networks have overlapping coverage areas, then the network communication through the networks is selected. The radio access networks 14 to 22 are here coupled to a core network 28 by a gateway (GWY) 26. A communication endpoint (CE) 32, which represents a communication device, communicates with the mobile station. The mobile station includes a radio transceiver having a transceiver circuit % capable of transceiving communication signals with any of the networks 129970.doc 11 200901556 14-22. The transceiver circuitry includes separate or shared transceiver paths that are configured to operate using standard operating standards and protocols for individual networks. The radio station further includes an embodiment of the present invention < an antenna 42. The support of the gastric antenna is operable at different frequency bands within which the transceiver circuitry and the radio access network can operate.

Therefore, the size of the antenna 42 is correspondingly small when the antenna can provide signal energy conversion at a wider frequency at which the platform can operate. Figure 2 illustrates an exemplary embodiment of an antenna of the present invention. The antenna has a lateral dimension 46 and a longitudinal dimension Μ that allows positioning of the antenna within the housing 44 (shown in Figure 1). For example, the substrate is 3 5 mm x 2 5 mm. The plan view of Fig. 2 is a, r丄, and the configuration of the conductive traces formed on a substrate 52 is illustrated. The substrate is formed by (or including) a non-conductive plate or portion that provides a surface that allows coating of a conductive material. The antenna 42 forms a hybrid strip antenna' having a set of radiating elements, a peripheral loop 56 and an L-shaped strip 58. The peripheral loop extends around the perimeter of the substrate and, in the exemplary embodiment, extends to a peripheral edge of the substrate to form a closed shape that defines an interior region 62. The inner region forms the second resonant element (the L-shaped strip 58). Here, the peripheral circuit 56 is rectangular, and the state 'is formed by four side portions corresponding to the four sides of the substrate 129970.doc • 12· 200901556 52. Thus, the length of the peripheral loop is defined by two laterally extending side portions and two longitudinally extending side portions. The length of the peripheral loop determines the first resonant frequency of the antenna at one of its resonances. The first resonant frequency is formed by appropriately selecting the length of the peripheral loop. Here, the first resonant frequency of the peripheral loop at its resonance is at a lower frequency band in which the mobile station can operate. » One of the side portions of the lee, where the top side portion (as shown) forms a curved catching line 66. The meander line 66 defines a meandering line length that is controlled by the number and size of the non-conductive fingers 66. Here, the interdigitated fingers of the interdigitated fingers 68 extend in a generally parallel direction, the number of which causes the meandering wire to have a desired length. The meander line is also resonant at the -resonant frequency' here - in response to the frequency of the higher frequency band at which the mobile station can operate. In one embodiment, the side portions of the meander line are formed first, and then the electrically conductive material of the side portions is engraved with the fingers. In another embodiment, the meander line forms part of a pre-configured pattern' which defines where the coating of the electrically conductive material forming the antenna is applied to the substrate (d). Tuning of the meander line and the peripheral loop is performed by changing - or a plurality of the fingers _ length. The L-shaped strip 58 is formed in an interior region defined by the peripheral loop %. One of the ends of the legs of the L-shaped strip extends to and electrically couples to the peripheral loop. Here, the end of the shorter leg of the (10) strap extends between the ground location 74 and the feed location 76 to the outer peripheral loop 56. Coughing or the like: the ground defines a contact connection with the feeding position 'to which the hybrid strip antenna 42 is turned to be shown in the transceiver circuit 36_). The L-shaped band Μ forms a 129970.doc -13- 200901556 vibrating cow, resonating at the wire frequency. The band 58 is resonated by its total: determined by its length. By appropriately selecting the length of the strip, the resonant frequency that causes the element 58 to resonate corresponds to a frequency at which the mobile station can operate. In the exemplary tactical scheme, the L-shaped band resonates at a frequency that is similar (ie, close, ^covered, or otherwise adjacent) to the frequency of the meandering line 66 at its resonance. . The antenna exhibits a stable_pattern and stable band characteristics at all of its resonant frequencies (here, the _9_800/1900 MHz band). Figure 3 is a graphical representation 86 of the antenna features of the exemplary antenna 42 of one of the specific embodiments.

Moreover, a passband 96 extends the n-line between the 2682 Hall 2 and 2038 MHz to convert the signal energy in the bands 94 and 96. The frequencies defining the frequency bands 94 and % are varied by varying the length of the loop %, the meander line 66, and the L-shaped strip 58. Because the substrate 52 defines the size of the hybrid strip antenna to be small, the hybrid strip antenna can be positioned in a compact mobile unit enclosure while also providing operation in multiple frequency bands, for example, at 800/900. The quadruple band of a quadruple mode mobile station operating at the /1800/1900 MHz band. Figure 4 illustrates a method flow diagram (generally shown at 1 〇 2) which represents a method of operation of one embodiment of the present invention. The method provides for the conversion of signal energy to a radio device. First, as shown in step 104, a first radiating element is formed around the periphery of the substrate. The first radiating element defines a loop that is configured to resonate within a first set of frequency bands 129970.doc • 14- 200901556. Next, as shown by step 106, forming on the substrate region within the loop extending around the periphery of the substrate - the second illuminating element 6 defines a L-shaped strip and is configured to Resonance within a second set of frequencies. Moreover, as indicated by step 108, the signal energy is converted within the first and second frequency band sets in which the first and second radiating elements resonate. • A compact hybrid strip antenna system that exhibits a stable radiation pattern and exhibits stable frequency band characteristics. Due to the small size of the hybrid strip antenna, the hybrid strip antenna is suitable for positioning in a small package, such as in a cover outside a mobile station.
