This paper presents the design of reconfigurable antenna for LTE (band1, band23, band40) and WLAN applications. The proposed antenna consists of rectangular patch fed by a proximity feed. The presence of square slots on the diagonal corners is used for frequency reconfiguration. The antenna can operate at 2.07GHz, 2.1GHz 2.4GHz and 2.45GHz by proper selection of diagonal slots. The directivity is greater than 5dB at all operating frequencies and the radiation pattern is directional in the elevation plane and omni-directional in azimuth plane. The simulation of the proposed antenna is carried out by using HFSS software. © 2013 IEEE.
