Fig. 4 shows the synthesized (red solid line) and measured frequency response (black solid line) of the implemented filter (inset Fig.4). The resulting coupling matrix of t implemented filter is shown below. The measured frequency response exhibits flat amplitude in the passband and no rounding effects are observed in the lower band edge of t! filter. The upper band edge is rounded because of t transmission zero produced by the existence of undesired cross-coupling between non-adjacent resonators. T ne ne ne ne implemented microstrip filter gives a transmission response (in the lower band edge of the passband) equivalent to higher (1000) Q filter response. a
