LRF – Laboratório de Pesquisas em Radiofrequências

Miniaturization is a primary concern today in communication
and biomedical systems. A highly miniaturized antenna
with electrical length 0.036λ  x 0.044λ x 0.005λ
(11.25mm×13.80mm×1.55mm) was implemented based on
the zeroth-order resonance approach. The experimental resonance
frequency presented a slight shift to the right due to the
limited resolution of the fabrication process. The detailing of
the design methodology presented here can be a useful guide to
antenna designers who are working on miniaturized antennas.
