Abstract

In this paper, we propose a multiple slotted dual-band square patch antenna with CP(Circular Polarization) characteristic. And we present the simulation and measurement results of the design example. We designed a slotted patch antenna by using computer simulation program, Zeland IE3D, and then some tuning followed with measurements. Measured -10dB bandwidths of $S_{11}$ characteristic are 127MHz($2.346GHz{\sim}2.473GHz$) for the low-band, and 122MHz($3.379GHz{\sim}3.501GHz$) for the high-band, respectively. And measured maximum gains and half-power beamwidths are 6.94dBi, $72.95^{\circ}$ for the low-band at 2.30GHz, 5.78dBi, $76.51^{\circ}$ for the high-band at 3.45GHz, respectively.
