Abstract

A miniaturised, dielectrically loaded bifilar/ quadrifilar antenna (MDLB/QA) is discussed briefly. Classified as an electrically small antenna, the approach to measuring its efficiency is described along with results from some measured prototypes. A probing method employed to discern the resonances for the differing modes of the antenna without the need for full pattern characterisation is also described.
