    Abstract: The development towards the microstrip filters
and their applications in different areas of satellite
communication and VSAT system on chip made the
scientists focus on the compact, lightweight and wide
beam filters. In this study, a wide band bandpass filter
utilizing quarter wavelength transmission lines is created
and analysed. Design equations are presented to calculate
the length and width of the quarter wavelength
transmission line. An equivalent lumped components
circuit, gotten from the proposed structure is introduced
and its components are presented. The proposed filter is
fabricated and tested to evaluate the suitability for
wideband applications. Various parameters such as
reflection co-efficient, transmission co-efficient,
bandwidth, group delay and quality factor are measured
and have made comparison with the simulated results to
verify its suitability for satellite communication
applications. Miniaturisation of the filter size finds the
suitability of a filter to be used for a smaller platform.
