In this paper, a compact parallel coupled microstrip band-pass filter (BPF) is used to design a wideband third order of the Tschebyshev elements for an unlicensed WiMAX technology. Some techniques based on the parametrical study are proposed to obtain the desired 10 % operating bandwidth filter response. The new filter is implemented on Arlon AR 1000 substrate having a relative permittivity of 10 and substrate thickness 1.1938 mm respectively. The results based on the transmission line theory approach and the commercial electromagnetic Agilent ADS and CST-MS simulators show a good agreement.
