ABSTRACT: A Printed monopole antenna was designed and
manufactured with the wideband performances in two frequency bands. The antenna
is compatible with WiMAX and WiFi standards. After reviewing a couple of
literatures, the antenna was designed, analyzed and proven for two central
frequencies, 2.5 GHz and 5.6 GHz, with much improved bandwidths. Finally, the
antenna was manufactured with the overall size of 4 cm × 4.4 cm on Rogers
(RO4003) substrate. The antenna is made into three L-shaped radiators. A 50 Ω
microstrip feed line connects the port to the two L-shaped radiators of
different lengths, thus providing two frequency bands. An inverted L-shaped
radiator is printed on the less radiation upped side, to tune the antenna for
wide band performances. The raised problem was solved with the integral
equation solver of the Ansoft high frequency simulator structure (HFSS-IE).
Optimal results are presented in this article: the simulation results in comparison
with measured results. This antenna prototype’s overall dimensions would be readjusted
according to any industrial and manufacturing requests.
