DESIGN OF COMBLINE FILTER FOR MICROWAVE P2P LINK

Microwave filters are an essential part of communication systems operating in the
specified frequencies range. The main challenges faced by the designers today are
reduction of power loss and size of the filters. This paper is intended to develop a
cavity combline bandpass filter for microwave P2P link in order to introduce it to the
Malaysian market. The report attempts to find a suitable solution to the present
demand in the market by offering a new design used in the field. The methodology to
be used in the process of the project includes calculation of the filter parameters,
designing the filter in Ansys HFSS software, simulation, designing layout of the
transmission lines, fabrication, testing, and tuning. The paper also highlights the
history of the microwave engineering development, and reviews the previous studies
and projects of different groups to use as an example and reference in the current
case. The project is the Final Year Project of a Bachelor of Engineering (Hons)
Electrical & Electronics Engineering student at Universiti Teknologi PETRONAS.
