Tripole-antenna for broadband system, has tunable inductor that is parallely connected with three coaxial cables when two switches are in open condition such that system operates in very high frequency

摘要

The antenna has three resonance frequency coaxial cables (K) that are connected with a tunable inductor (L). The inductor is switched off and a broadband system operates in fundamental frequency when one of two switches is in closed condition. The inductor is parallelly connected with the cables such that the system operates in very high frequency when the two switches (S1, S2) are in closed condition.
