Abstract
As the applications of mobile phones are increasing drastically, the need for small physical structures and low volume of antenna with less weight are appreciated. To meet the multiple frequency operations, reconfigurable antennas are suggestible candidates. A reconfigurable antenna is an antenna in which whole volume can be operated at different bands, which results the physical size of the multiband antenna can be reduced. The property of reconfigurability is attained in this paper by combining a Planar Inverted F antenna with a spiral structure appended with diodes. A significant improvement in gain is observed by switching different diodes on the antenna structure and shift in frequency bands is noticed. The simulation study with Ansys HFSS made the task simple to virtualize the antenna performance characteristics before the practical design with PIN diodes. The analysis of designed antenna is clearly analyzed with diode positions and switching operation.
