Abstract:

The planar dipole antenna, an antenna feed of which is differs from the known variants of the classical symmetric dipole by a new method of excitation, is considered. In the absence of absorbing materials in the design of the proposed antenna, the bandwidth of its has a frequency overlap band over the range of more than 10:1. Also under the this criterion a proposed dipole is a ultra wide band antenna. With regard to a radiation pattern the said bandwidth is not so wide. Performance in both the frequency domain and time domain for this antenna has been investigated and revealed its a substantiale feature in comparison with usual dipole antennas as for polarization behavior and gain in presence of a conductive plane. This features of a proposed dipole allows recommend its as new alternative candidate for efficient using in existing and new frequency ranges of information systems.
