To introduce the concept of key shaped slot in PIFA antenna for wireless applications and to obtain multiband frequencies. The antenna resonates at various frequencies which can be used for various applications in the latest wireless devices. Currently there is a need for multiband antennas in order to minimize the active profile. The concept is to increase the number of frequencies on a single active plane and to increase the bandwidth. The numbers of frequencies of the antenna are increased using slots which also improve VSWR & return losses. The CAD FEKO software has been used to simulate the antenna.
