Abstract :
Both 300- and 570-MHz versions of an electrically small, coaxially fed Z antenna were designed and tested. These two cases demonstrate the ability to change the resonance frequency of the Z antenna by changing the value of its lumped element inductor. The numerically predicted and measured results are in good agreement.
