Broadband UHF Antenna with Controlled Current Distribution for Radiocommunication Systems

This paper presents results of the computer-aided design of a new broadband monopole UHF antenna with controlled current distribution (BACCD) for different radiocommunication systems. General structure, computer model and construction of the antenna BACCD are proposed. Optimal broadband matching of the antenna is fulfilled in the work. A method of computer electromagnetic simulation of the whole antenna is described. Frequency characteristics, electromagnetic radiation, near electromagnetic field and current distributions along the antenna BACCD for wide frequency band are calculated in the work.
