Abstract
A broadband bicone antenna supports frequency selective control of electrical length. Frequency selective control of the electrical length of an antenna can provide an antenna exhibiting two or more different electrical lengths where use of each length depends upon the operating frequencies of the signals. The electrical length of the bicone antenna may be reduced in response to higher operating frequencies. Such reduction in electrical length at higher frequencies can provide improved antenna radiation patterns for the antenna. Further, the electrical length of the bicone antenna may be increased in response to low frequency operation. Such increase in electrical length may improve VSWR performance at lower frequencies. Simultaneous operation of the bicone antenna at varied electrical lengths for varied frequency bands can provide improved broadband performance of the antenna.
