Abstract: Digital Video Broadcasting (DVB) is an emerging broadcasting technology and internationally accepted open standards for digital television (DTV). DVB-T (Digital Video Broadcasting - Terrestrial) is a terrestrial digital video broadcasting technology standard allowing network design provide a wide range of services, from HDTV to multi channel SDTV, fixed, portable, mobile, and even handheld reception. Passive radar is an emerging radar concept that utilizing non-cooperative sources of illumination in the environment to detect targets without disclose its own presence. This project is to study and design of a few types of antennas and filters for DVB-T based passive radar demonstrator. In attempt to get familiar with the performance of these two parts of DVB-T based passive radar systems, simulations using the state of the art software are processed. The mam characteristics as well as the comparisons and optimizations of dipole antenna, biconical dipole antenna and half-arm biconical dipole antenna are shown in the thesi s. The width of the dipole arm makes components to the bandwidth and reduces the length ofmicrostrip line and dipole arm. Hairpin, Corner perturbation, Center perturbation, comb and butterfly filters are also design in this thesis. By adjusting the quadrant wavelength, the desired center frequency of filter can be obtained.
