The input impedance and radiation characteristics show the broadband operation for 1.0 GHz to 4.5 GHz. Next, the actual gain of the active transmitting antenna consisting of amplifier circuit and monople antenna is formulated. The scattering parameters of amplifier circuit of the transmitting antenna are examined by using the circuit simulator "S-nap", and the actual gain of this antenna consisting of the amplifier circuit and the monopole antenna is calculated., The 2000 Asia-Pacific Symposium on Broadcasting and Communications (APSBC'2000) .
