Abstract

A stacked patch microstrip antenna combined with a stacked ring microstrip antenna is proposed for quadruple band operation. The two antennas (a stacked patch microstrip antenna and a stacked ring microstrip antenna) are excited by an L-probe feed. The impedance bandwidth is enhanced by using double resonance at all frequency bands. With simulations, the relationships between the antenna´s geometrical parameters and operational frequencies are clarified. The operational principle for quadruple band is explained by the simulated electric currents. The antenna is designed for Wi-Fi (2.45/5.25/5.6 GHz bands) and mobile WiMAX (3.5 GHz band).
