چکیده انگلیسی
To achieve an improved stopband response including expanded stopband width, increased rejection level, and a smooth S11 phase response, a lowpass filter (LPF) is proposed based on the suspended microstrip line with naturally high characteristic impedance and the radial stub with intrinsic transmission zero. The usually unmentioned phase response, are critical to obtaining a wide and flat operating band for the microwave detector, since a smooth phase response exerts small load effects to the diode. As a demonstration, a detector employing the LPF is fabricated and measured. The measured results show that a wide operating band from 1.8 to 13.5â¯GHz with flat detection outputs of ripple less than 1â¯dB is obtained for the detector, which coincides with the smooth-phase range of the LPF.
