Comprehensive analysis of broad band wired antennas

Although the wire antennas are some of the oldest, simplest, cheapest, they are in many cases most versatile for many applications. Since one of the main objectives in the design of an antenna is to broadband its characteristics, so this paper presents a comprehensive analysis of three broadband wire antennas: V-normal mode helical antenna, biconical wire antenna, and the uniconical wire antenna. The ready made software simulator (NEC-PRO software code) is used to investigate the characteristics of the presented antennas and to study the effect of the half cone angle as well as the included angle on the performance of the antennas.
