Abstract
One compact printed monopole antenna with a chip
inductor for dual-bandWLAN is presented. The proposed antenna
has a two-armed structure and an electrically small size. The equivalent
circuit structure of the chip inductor is studied and a simplified
circuit structure is proposed. This simplified circuit structure
was introduced into the electromagnetic (EM) simulation model by
assigning a RLC boundary condition, and the experimental results
show that with this model, the simulation can provide an accurate
prediction of the antenna radiation performance. The measurement
results show that the proposed monopole antenna has a
VSWR 2:1 bandwidth over 2.41-2.49 and 5.2-5.6 GHz with omnidirectional
radiation patterns. The simulation results suggest that
the proposed antenna has a directivity around 1.5 dB at both bands
with relatively high radiation efficiency. The antenna is designed
and optimized by using Ansoft HFSS.
