The access point φ (Access Point) of the multi-input and multi-output antenna device is for the purpose of high performance. [Prior Art] In any communication system that uses radio frequency (Radio Frequency; rf) to transmit signals, the effect of ''multipath') transmission should be considered, after the desired signal is reflected from the source of the signal source and the receiving antenna. Multipathing occurs when multiple required signals arrive at the receiving antenna. The conventional multipath problem is the signal loss (Dr〇p〇ut) caused by multipath phase cancellation, which occurs indoors and often causes signal loss. Multipath condition, because the output of the wireless transmitter is emitted in all directions and is reflected from many types of surfaces in the room, but in reality, wireless systems operating indoors will continue to generate approximately several indoors. Hundreds of reflections, but because the direct path # is usually the strongest signal of all signals, its multipath condition may also occur outdoors, especially from the reflection of cars, signboards and metal building surfaces; solve the above multipath problem , usually processed in the following way, by means of 'space diversity' (Spacediversity) of more than one antenna It connects several antennas to a receiver, and the system decides the k-level and uses the antenna with the highest signal. The antennas are physically separated from each other by 5 M303502, that is, they have spatial distribution. In order to combat the age of the signal, and thus improve its signal quality, the required interval depends on the degree of multi-channel (four) degree extension, but at least half the wavelength of the work should be fresh to ensure that the antenna JL reception has no correlation (with diversity) Signal to fully realize the benefits of diversity reception; see Figure - for the use of multiple input and output antennas for multiple sets of printed antennas and multiple sets of boards, between the printed antennas, ie the first board A first printed antenna u and a signal feeding point 110 are disposed.
