Designing of Reconfigurable Multiband Antenna for WLAN Application
2013
Remarkable equipment development in the field of communication and the growing end user requirement has lifted the need for multi-functional wireless communication devices. Since antenna is the basic part of each wireless communication scheme and multi-functional antennas are looked-for to meet up the requirements of present progress, those be able to sustain compound functions in a particular antenna constituent by sustaining other than one operational frequency . For this reason reconfigurable multiband antennas can be used basically to lessen the amount of antennas needed for projected system application. Moreover, conventional antennas are deficient in the ability to adjust as altering operating situations that could limits the system performance. Consequently, the use of reconfigurable antennas helps out to overcome incapability of conventional antennas and improve the system recital for example in applications like as cognitive radio where system parameters differ with the changing in circumstances. This thesis purpose is to design of Reconfigurable Multiband Microstrip Antenna equipped with the competence of fine-tuning one of its functioning frequencies independently. Varactor diodes are used, and the capacitance range from 1 pF to 10 pF are engaged to get reconfigualbility and High Frequency Structure Simulator (HFSS) V 13 software tool is used to carry out the antenna designing.
