Bandpass filter design with spurious frequency reduction capability
Passband microstrip coupled line filter are widely used in daily microwave engineering practice. There are various topologies to implement microstrip bandpass filters such as end-coupled, parallel coupled, hairpin, interdigital and combine filters. This thesis discusses design, simulation, fab...

| description | Passband microstrip coupled line filter are widely used in daily microwave
engineering practice. There are various topologies to implement microstrip bandpass
filters such as end-coupled, parallel coupled, hairpin, interdigital and combine filters.
This thesis discusses design, simulation, fabrication and testing using microstrip
technology. The choice of a parallel coupled filter topology is discussed and an
application of the grooved substrate is presented to suppress the first spurious of
Parallel Coupled Microstrip Bandpass Filter (PCMBF). Band pass filters (BPF) are
significant role in wireless communication systems. These filters present an
undesired pass band at twice the design central frequency of the filter. The
narrowband with spurious suppression is achieved by using two stage PCMBF, BPF
was designed by replacing the tight couplers are arranged at the input and output of
the filter whist the weak couplers at the middle section of the tight coupler with
optimize groove. By using Sonnet Lite software it shown the BPF with 2.99GHz cut
off frequency and bandstop of to 7GHz has been simulated and fabricated on Flame
Retardant 4 (FR4) substrate by using etching process. Significant spurious
suppression up to 33.23dB is measured at 5.96GHz. |
