In this paper, a planar frequency reconfigurable antenna operating at LTE bands is introduced. The proposed antenna, with dimensions of 60*30*0.8 mm3 and its frequency bandwidth is suitable for using in smartphones and tablets. Antenna frequency controls by a pin diode. These frequencies are LTE3 (1.8GHz) with range of 1.75-1.85 GHz and antenna gain is 1.56dBi and LTE-7 (2.6GHz) with range of 2.45-2.78 GHz and antenna gain is 1.95dBi. The measured results and simulation have proper adjustment with each other.
