Abstract:
In this paper, a new method for designing an active dual-band dipoleantenna is proposed. The operating frequencies of the proposed antennaare 150 and 450 MHz that are usually used in military applications. Usinga series stub is the main idea in the proposed dual-band antenna, where itmakes an independent resonance frequency higher than the mainresonance frequency of a conventional dipole. To make appropriateimpedance matching in the two frequency bands, the technique ofcreating an internal coaxial cable is used. Furthermore, to improve theantenna gain, an amplifier is in series part connected to the proposeddipole antenna. The simulated and measured results of the return loss,radiation patterns and antenna gain show that this antenna has a goodoperation in both resonance frequencies
