[Prior Art] The main goals of wireless communication today include high speed, power saving, low transmission power and low cost. The _ _ wireless __ (WLA Shun Lan Liu her oth) system will not continue to meet the requirements of people to transfer a large number of digital data. On the other hand, there is a 4α in human 4's emphasis on the health problem; wireless electromagnetic waves with too much traffic will be harmful to human health; therefore, a wireless communication system with low transmission power is currently the most urgently needed. In the general wireless communication secrets, take the receiver as an example. The RF circuit is located in the phase of the transceiver system. The RF signal is received by the antenna (Antenna), and then the local oscillator (LO Signal) is provided by a filter, low noise amplification (LNA), and by a voltage controlled oscillator (vc〇). The RF signal is down-converted to the intermediate frequency signal (Positive Signal) in the Mixer, and the final input is input to the signal processor and converted into the required fundamental frequency information. In the RF rigid-end circuit, the filter H is usually located at the back end of the antenna. Its main purpose is to filter unnecessary signals, select some signals to pass, and block other signals. The filter is also a key passive component. For example, the rugged phone accounts for nearly 65% of the area on the motherboard; the filter is a valuable component. Because the frequency characteristics of the filter will indirectly affect the accuracy and distortion rate of the back-end circuit when processing the signal, it can be seen that the quality of the filter frequency characteristics will determine the quality of the wireless communication system. M295345 . A has to provide a wireless communication system with high power transmission capacity and low Wei, the Ultra Wide Band (UWB) system can achieve this goal. The ultra-wideband system is the -__Wireless Personal Area Network (WPAN) technology standard. UWB's spectrum range is very wide, from 3432MHz to 1〇296MHz, with 528MHz as a single band, the spectrum is cut into 5 channels, which can be used for high-speed and large-scale data transmission (up to 5) 〇OMbPs). In the UWB system communication standard set by the US Federal Communications Commission (4) (10) 丨c〇m_icati〇ns Commission, FCC), the 3_ sufficiency ratio should be greater than 〇%. In order to meet the UWB frequency response, in the UWB RF front-end circuit, many main crane components need to be recorded, _ is the most functional RF passive component-filter. In traditional wireless communication systems, such as ffiEE 8〇2n/a/b/g and the bud system. The filter is mostly used to construct the frequency response of the narrow band (Narrow band), and the filter used for the axe ten-frequency response. In order to comply with the frequency response of UWB, the filtering of the traditional narrowband f is not applicable. There is a need to redesign a filter with ultra-wideband characteristics. > In order to solve the above problems, it is desirable to provide an ultra-wideband filter to overcome the disadvantages of the prior art. The job is the reason, the applicant is careful testing and research, and a perseverance spirit, finally researched a plurality of finger-inserted turning lines, using the face-enhanced electromagnetic filial horse to form the ultra-wide band Characteristic filter.
