Collapsible wide band width discone antenna

摘要: A collapsible discone antenna is provided with an ultra wide band width by providing a conical skeleton cone, the rods of being meander lines so as to effectively reduce overall dimensions factor 2, electrically interconnected at their distal ends eliminate performance degradation due varying ground conductivities. specialized feed configuration used in one embodiment multiple antennas stacked above low disc through utilization or more coaxial which are wrapped around ferrite toroid that they may be passed up low-band without detuning antenna. The use inductor between cone and further reduces frequency cutoff markedly decreasing VSWR frequencies 20 megahertz.
