Various types of charms have also emerged in the aftermath of the rain. In order to make the product more competitive in the market, designers should try to reach the goal of = light weight, small size, foreign job concept, work shirt-like, and low cost. The redundant and small size is called domain mobility; the diversified functions can win the favor; and then start with the modular design of the whole barrel ’to simplify the process of production and maintenance to reduce costs. From this perspective ^ The antenna design in mobile communication systems is good or not, which almost dominates product quality and market power. Among the antennas that meet the requirements listed above with less money, the inverted F-shaped flat panel antenna is one of them. The inverted F-shaped flat antenna has a simple structure and can be concealed inside the communication device without shaping the appearance. At the same time, it is easy to integrate with the circuit, which is extremely superior in the robustness of mobile communication systems. Printed by the Central Standard Bureau of the Ministry of Economic Affairs and Consumer Affairs Co., Ltd. Generally speaking, the inverted F-shaped flat plate antenna is a resonant antenna. On the structure, because the first end of the radiating metal sheet is grounded, the first resonance mode is a four-blade wavelength resonance, so it can have a smaller half-wavelength / vibration than the general flat antenna volume. However, when applied to mobile communications, the size of this inverted-F flat antenna is still too large. Taking the current GSM 900 MHz system as an example, the operating wavelength of this band is about 33 cm. If an inverted F-shaped flat panel antenna with a quarter-wavelength resonance is used, the long side size and force of the radiating metal sheet are about 8 cm. Antennas of this size must be clunky if they are to be attached to the mobile phone or hidden in the shaft of the hand. -Generally, the method is to implant a U-shaped slot (slot) or an L-shaped slit in the radiation metal sheet, and use

The structure proposed by Beni Riqi even folds the light-emitting gold f toward the Tianle Department to further shorten the scale of the inverted F-shaped flat antenna and reduce the antenna brain. Riding near the feed point of the antenna of the antenna of the present invention has a rectangular notch. By adjusting the size of the notch, the frequency ratio of the first two resonance frequencies of the round-shot metal sheet can be close to 2. _ The double-handed operation of the loot, the antenna volume designed by the supporter of the present invention on the same day is only 7 2 χ⑴χ% coffee 3, so it has extremely high industrial application value. /, -1 Riding indication 'The dual-frequency inverted F-shaped flat panel antenna 1 of the present invention includes: two == U pieces, a grounded metal surface 12, a coaxial feeder & material 4, and a base 15.
