Multi-band frequency tunable LTE antenna for mobile phone applications
The progress shown in mobile phone technology in dealing with multiple band transmission and high data transmission rates has been followed by an increased demand in favor of rich content mobile services and new functionalities. To provide these services, multi-band and wide-band antennas have to be integrated into the compact structure of modern mobile phones. In this paper, as part of the results of a research project, we propose a multi-band, frequency reconfigurable main antenna along with a receive diversity antenna for use in 4G (4th generation) mobile terminals. The main antenna is a Planar Inverted F Antenna (PIFA) mounted on bottom of the mobile phone and grounded by a variable reactance for operation in 790–960 MHz and 1710–2690 bands covering GSM, DCS, PCS and UMTS standards. The receive diversity antenna on the other hand is a monopole antenna to be operated in the 1710–2690 MHz band. Use of LDS (laser direct structuring) structure in both antennas are proposed for fine-tuning of their response. Simulated frequency responses of reflection coefficients and radiation patterns of the prototype antennas are given.
