Abstract

In this letter, a low-profile planar microstrip antenna is proposed to operate at lower WLAN (2.4 GHz) and WiMAX (3.5 GHz) frequency bands. The antenna has good omnidirectional radiation pattern for both the bands with compact form-factor. The obtained result shows that the proposed dual-band omnidirectional microstrip antenna has better impedance bandwidth and high radiation efficiency while maintaining the structural compactness. The electromagnetic model of the proposed antenna is developed in CST Microwave Studio for analysis and optimization. The fabricated antenna and measured results are presented.
