The planar sleeves antenna with two sleeves is numerically analyzed and its wideband characteristics are examined. The antenna is excited by the coplanar waveguide with characteristic impedance of 50Ω. The characteristics of the planar sleeve antenna are calculated by using the electromagnetic simulator IE3D based on Method of Moment. The design frequencies of this antenna are 3.5 GHz and 3.7 GHz. The calculated current distribution and radiation characteristics indicate that the sleeves work effectively at design frequencies. The return loss characteristics are improved by adjusting the length of radiating elements.
