This paper presents a triple-band rectangular patch antenna that can be operated in three different resonance frequencies of 2.40 GHz, 3.50 GHz, and 5.80 GHz for WLAN and WiMAX applications. The FR-4 substrate with dielectric constant of 4.3 is used, with the dimensions of the substrate 34301.6mm3. The performance of the rectangular patch antenna has been simulated and measured and the proposed patch antenna operates at three different resonance frequencies of WLAN and WiMAX which are 2.35-2.54 GHz, 3.45-3.57 GHz and 5.74-5.83 GHz. These results correspond to a simulated bandwidth of 197 MHz, 118 MHz and 90 MHz. The radiation pattern of nearly omni-directional is obtained. Overall, the results obtained show the designed antenna have a good performances of the three operating bands. © Published under licence by IOP Publishing Ltd.
