In fact, the multi-frequency antenna is a dual-band antenna (duaiband antenna), which can be used to distinguish the low frequency band and the high frequency. Frequency band. - Two single-pole inverted F-type flat-panel antennas 42 for the left and right sides of the antenna towel. The area of each antenna 42 is limited to 2 〇mm* 25mm* 5mm cubic volume range ❹ within the wire reduction, the antenna of the antenna, That is, the combination of the scalar feeder and the receiver. The front panel of the printed panel antenna is a receiver that functions as a receiver. The fourth diagram is used to illustrate the single-pole inverted F-type panel antenna 42, please refer to the fourth figure, and the fourth figure is a schematic diagram of the multi-frequency antenna of the present invention. Although the printed type is flat, the antenna 40 is also a multi-frequency antenna 'but similar to the antenna disclosed in the patent application No. 9, the special multi-frequency antenna of the present invention refers to the left and right sub-sections. Single pole inverted F type panel antenna 42. ❹ The single-pole inverted F-type panel antenna 42 is also disposed on the substrate 32, and is also used for the light-low frequency band and the high frequency band. The single-pole inverted F-type panel antenna 42-step includes a low-frequency inverted-F (10) phantom radiator, a low-frequency microstrip light-emitting body 52, and a high-frequency light-emitting body 54. The low frequency inverted F type radiator 50 further includes a low frequency radiating portion 5002, a grounding light emitting portion 5004, and a feeding radiation portion 5?. The low frequency modulating portion 5002 is disposed laterally above the substrate 32 and maintains a field distance from the substrate %. The grounding radiating portion 5004 extends laterally from the middle portion of the low-frequency radiating portion 5〇〇2, and the turning portion extends toward the substrate 32 to engage a grounding point 6〇. The feed-in radiation portion 5 〇〇 6 series 9 2009 39 569 and the ground patch portion 5 GG 4 are juxtaposed and extend laterally from the end of the low-frequency lap portion 5 to extend toward the substrate 32 to engage the feed point 62. The feed point 62 and the ground point 60 are disposed on the substrate. The bass-low-frequency microstrip radiator 52 is juxtaposed with the grounded radiating portion 5_ on the other side of the opposite human firing portion 5G06 and extends laterally from the other end of the low-frequency light-emitting portion 5. The low-frequency microstrip light-emitting body 52 further includes a health-time microstrip portion 5202. The low-frequency sub-microstrip portion 52G2 is from the low-frequency micro-slip.

In the fifth step of the step-by-step money, the fifth figure is the simulation of the money record of the single-pole inverted F-type flat panel 42 antenna 42 of the present invention. The invention of the rural frequency antenna structure 30 is simulated by HFSS. As can be seen from the fifth figure, it is true that the dual-frequency performance is generated near the low-end section of 2. 4 GHz and near the high-frequency band of 5.2 GHz (return to the ordinate) Loss): -l〇 the following curve), and its bandwidth is effectively increased, especially the bandwidth of the 5·2GHz band is in the range of 4.6GIIz to 6.5 GHz (strictly at least 4.95GHz to 5. 85 GHz range), and ideally increase the bandwidth effect.
