摘要： On the internal surface of each of the through-holes formed in a dielectric block, an internal conductor is formed, while on the external surface except the top surface, an external conductor is formed. The internal conductors, together with the external conductor and the dielectric block, form dielectric resonators with 1/4-wavelength using the top and bottom surfaces of the dielectric block as an open surface and a short surface, respectively. Each of the through-holes has a large-diameter hole portion and a small-diameter hole portion and also has a coupling adjustment hole portion for the purpose of a fine adjustment of electromagnetic coupling between adjacent the dielectric resonators.

摘要： A multilayer dielectric evanescent mode waveguide bandpass filter with resonators utilizing via hole technology is capable of achieving very narrow bandwidths with minimal insertion loss and high selectivity at microwave frequencies is provided. The resonators may also be used as feed posts. A typical implementation of this filter is fabricated with soft substrate multilayer dielectrics with high dielectric constant ceramics. This filter typically takes up less space than other filters presently available. A typical implementation operates at a center frequency of 1 GHz, although other center frequencies, such as approximately 0.5 GHz to approximately 60 GHz, are achievable. The perimeter of the filter may be defined by via holes or plated slots.

摘要： The present invention relates to a microwave filter, having U-type resonators, which passes a desired frequency signal and removes an undesired frequency signal when used in a high frequency antenna circuit for wireless communication systems. In accordance with the trend of reducing communication system terminals, it is required to reduce a high frequency filter. The high frequency filter is required to attenuate signals very sharply at the stop band especially near to a passband transmitting and receiving frequency, so as to improve the efficiency of the frequency. The filter may be reduced in weight by forming U-type resonators instead of straight-type resonators. Excellent attenuation characteristics may be achieved at the stop band lower than the passband, using the difference of the characteristic impedance between the open end portion and the shorted portion of the resonator by forming the coupling control grooves at the outer walls of the dielectric block.
摘要翻译：本发明涉及一种具有U型谐振器的微波滤波器，当用于无线通信系统的高频天线电路中时，该滤波器通过期望的频率信号并去除非期望的频率信号。根据减少通信系统终端的趋势，需要降低高频滤波器。需要高频滤波器在阻带处非常清晰地衰减信号，特别是靠近通带发射和接收频率，以提高频率的效率。通过形成U型谐振器而不是直型谐振器，可以减小滤波器的重量。通过在介质块的外壁处形成耦合控制槽，可以通过使用谐振器的开口端部分和短路部分之间的特性阻抗的差异，在低于通带的阻带处获得优异的衰减特性。
