The proposed antennas were designed for single band at 2.45 GHz and dual bands at 3.3 - 3.6 and 5.0 - 6.0 GHz to support WLAN/WiMAX applications. The proposed single and dual band antennas showed omnidirectional radiation pattern with the gain values of 3.5 dBi at 2.45 GHz, 4.0 dBi at 3.45 GHz, and 3.3 dBi at 5.5 GHz. The dual band antenna array was placed on both top and bottom layers to obtain the desired antenna characteristics. The proposed double-sided dual band antenna provides omnidirectional radiation pattern with high gain.展开更多

The proposed antenna consists of six simple rectangles, whose geometry resembles all the “hand” of man. By varying the geometries and dimensions of these six rectangles, five different resonance modes can be effectively created for five distinct frequency bands, respectively. The overall dimension of the proposed antenna can reach 45 × 50 × 2.54 mm3. The simulated results show that the presented antenna is adapted to 4.6/5.24/5.6/6.7/7.3 GHz five bands which are applied to C-band.展开更多
