Abstract
A new microstrip-fed printed monopole antenna which is simple in design and compact in size is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) bands. A simulation software package, CST Microwave Studio, has been used to model the proposed antenna, whose electrical characteristics and radiation performance are thoroughly analyzed as well. The proposed antenna, with small size of 28 × 51 mm2 on Rogers RT/Duroid® 5870 substrate with permittivity 2.33, was designed and fabricated. It was demonstrated that the measured 10 dB bandwidth for return loss is from 1.76 to 2.59 GHz, 3.44 to 3.89 GHz and 5.18 to 5.99 GHz, covering all the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX bands.
