Wire-loaded monopole antenna

A new antenna is proposed for use in mobile communication systems. Detailed investigations are presented through the results obtained using numerical simulation (the method of moment technique). The wire-loaded monopole antenna has proved many attractive features so that it is recommended to be used in hand held units. The design of the antenna considers simplicity, compact size (65% of monopole height), and low cost. It has an omnidirectional radiation pattern in the horizontal plane with a very high gain (about 6-7 times of monopole antenna). The input impedance matches the feeding line ensuring perfect transmission of energy between the antenna and coaxial cable.
