资源简介：
An electrically-small electro-quasistatic exciter isdemonstrated using a counter-wound normal mode helical antenna. The arms are counter-rotated to cancel the generation of magnetic fields in the quasi-static regime. The field equations are derived and verified to show the degradation of magneticfields with minimal effects to the electric field. The long wire lengths give sinusoidal current distribution and fields that are not strongly dependent on the feed structure. As a result, the measured electro-quasistatic field agrees well with dipole behavior over long ranges. In addition, the circuit model for the antenna is presented and verified with measurements.
