Abstract
In
this paper, a novel quasi-lumped element resonator antenna is
presented. The proposed antenna consists of the interdigital capacitor
in parallel with a straight line inductor and is fabricated on Duroid
RC4003C circuit board. The entire arrangement was fed by a coaxial feed
at a frequency of 5.8 GHz. The size, bandwidth and radiation patterns
were studied. The proposed antenna exhibits better impedance bandwidth
and significant size reduction in comparison with similar results
obtained from the conventional microstrip patch antenna with similar
feeding technique and resonant frequency. The size of the proposed
antenna structure is 5.8 × 5.6 mm2 and experimental results are shown to be in good agreement with the design simulation.
