The presence of a capacitor with the resonant medium in a core essentially changes a character of THz radiation of photoconductive antenna. We obtain a coherent radiation at the frequency of elementary excitation (LO phonon or plasmon). The power of this radiation a little differs from a usual THz source. The energy of pulse to the suggested source is much more than the energy of a usual source because of the greater duration of radiation. It is possible to use this process as a new method in spectroscopic investigations.
