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.
