Abstract :
In this paper, a single grooved wideband Parallel Coupled Microstrip Bandpass Filter (PCMBF) with improved passband response and first harmonic suppression is described. The suppression of first harmonic spurious response was done by using a transmission zero frequency realignment method. The realignment was done by using a single groove with specific dimensions. The transmission zero and first harmonic frequencies can be realigned by varying a single groove size which is located at the center of the Parallel Coupled Microstrip Line (PCML). The wideband with harmonic suppression is achieved in three- stage PCMBF by using two single-stage bandpass filter of identical tight coupler with optimized grooved.
