Thomas Thatapudi, Jesse Jackson Sikha

Abstract


In this paper design of multi band PIFA for LTE/GSM mobile application is manifested. A matching circuit is employed in addition with the proposed arial costructed by  a rectangular plate placed on top of the FR-4 dielectric substrate of 65x80 mm2 size to provide wide operating frequency band. The ground plate is coated on substrate of its  bottom side. The proposed design is suitable for embedding in the mobile handset abd has advantages in aspects like low profile, small size, and good gain. Overall size of PIFA is small enough to be embedded in a smart phone, and it has been optimized to cover the LTE and GSM bands at 2600, 1500, and 800 MHz frequencies respectively.  The study of antenna’s performance in term of impedance bandwidth, S-parameters, radiation pattern and gain is presented with simulation results.
