[New technical field] This creation relates to a multi-band antenna device 'especially refers to a large enough to increase the isolation between the low frequency band and between the high frequency band The innovative high isolation structural type designer. [Prior Art] According to the rapid development of wireless communication, many communication products tend to be miniaturized, and the antenna requires a small size and an internal-architecture design to meet the overall aesthetic appeal of the product. In terms of general inverted F-type antennas, the bandwidth can be increased due to its wider transmission structure; the PIFA antenna can change the geometric appearance of the flat panel, and the transmission and reception effects of dual-frequency or even three-frequency or higher. Frequency antennas are quite common in built-in electronic devices. However, the disadvantage of the PIFA antenna is that the lower the frequency, the smaller the bandwidth with the monopole antenna, and the more difficult it is to design. In addition, many wireless information requires diversification or multiple input and multiple architecture. In these cases, the isolation between adjacent antennas is particularly important, so it is best to achieve higher isolation. The interference state of the antenna is reduced to the last check. It is known from the prior art that when the conventional piFA antenna is designed for multi-frequency lines, if applied to a multi-antenna system, the degree between the low frequency bands (such as the range indicated by B1) ) and the isolation between the high frequency bands (such as the range of the circle) will roughly fall between -15dB and -20dB, which is as shown in the figure. However, there is still too much interference in the isolation. The space and necessity exist. It is based on the problems existing in the conventional multi-band antennas, and it is an innovative structure with more ideal practicability. It is necessary for the relevant industry to develop the energy-distribution products so that the comparison agreement can be achieved.
