[Prior Art] Press, with the rapid development of wireless communication, whether it is a laptop or I is a mobile phone has developed rapidly from dual-frequency to multi-frequency, and multi-frequency design to handle various signals, such as network, Bluetooth, GPS Etc., because all of these signals work at different bandwidths, and need corresponding antennas to match 0 in the conventional antenna, an inverted F-type dual-frequency antenna is used to receive a first frequency and a second frequency. a signal, and the antenna is provided with a first-plane conductive element and a second planar conductive element, and the bandwidth, impedance matching and gain are adjusted by the shape of the first planar conductive element and the second planar conductive element; The second planar conducting component: The upper portion of the area generally affects the gain of the antenna. If a higher frequency wide antenna is required, the substrate area must be increased. Therefore, the conventional antenna is often limited to the team. In addition, the space limitation of the I-set is not able to effectively enlarge the base plate area thereof effectively, resulting in the inability to have a higher bandwidth; and when the second plane conducts the π-piece area too large, it is easy to cause conduction with the first-plane. The component is indirectly broken. 3 M379187 In the conventional antenna, the bandwidth, impedance matching and gain are adjusted by the shape of the conductive elements and the distance between them, but the effect is quite unstable, because the distance between the conductive elements is easily designed to cause signals.
