摘要： A microstrip cross coupling bandpass filter includes an input port, an input resonator, an output port, and an output resonator. The input port and the input resonator are electric-coupled, and the output port and the output resonator are electric-coupled. A cross coupling gap corresponding to the distance between the input and output resonators forms magnetic coupling. The bandpass filter further includes a cross coupling line electric-coupled with the input and output ports. The cross coupling gap generates an attenuation pole on the high side of a passband. The attenuation frequency of the attenuation pole can be varied with the distance of the cross coupling gap. The cross coupling line generates an attenuation pole on the high and low sides of the passband.

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.
