Abstract
A compact frequency reconfigurable double slot antenna for wireless communication is presented. The proposed antenna consists of double slot with six RF PIN diodes placed at different position on the ground plane to achieve frequency reconfigurability. Based on the switching state of the PIN diode the antenna is capable of operating at eleven different frequency ranges. The radiation pattern of the antenna is nearly omnidirectional for all the frequency bands. The simulated return loss for all the frequency bands meets the optimum value. The overall dimension of the antenna is 30 × 25mm2 including ground plane. For different switching state, the antenna can operate in both single and dual band mode. Without changing the size of the antenna the antenna can operate in single band and dual band mode by changing the state of the RF PIN diode. The antenna parameters such as VSWR return loss and radiation pattern are simulated. The analyses are performed using Ansoft HFSS v13.0 software.
