In this paper, a novel reconfigurable open slot antenna has been proposed for LTE smartphone applications to cover a wide bandwidth. The antenna is located at the bottom portion of the mobile phone, thereby occupying a small space and providing mechanical stability to the mobile phone. Varactor diode is used to cover the lower band frequencies, to achieve a good frequency coverage and antenna miniaturization. The operational principles of the antenna are studied, and the final design is optimized, fabricated and tested. It has achieved the desired impedance bandwidth and the total efficiency of minimum 50% in free space throughout the required bands. The antenna performance with mobile phone components and human hand has also been studied.
Furthermore, the SAR in a human head is investigated and is found to be within allowable SAR limits. Finally, a Multiple Input-Multiple-Output antenna configuration with high isolation is proposed; it has an identical reconfigurable open slot antenna integrated at the top edge of the mobile phone acting as the secondary antenna. Thus, the proposed antenna is an excellent candidate for LTE smart phones and mobile devices.
