In this paper, the authors describe the design and simulation of four frequency reconfigurable three element log-periodic microstrip antenna arrays. A comparative study is presented using rectangular, square, triangular and circular patch elements. The three patches fed by inset feed line technique are connected with a single transmission line by a log-periodic array formation to form a wideband frequency from 2.9 to 3.4GHz. By applying three PIN diodes modules at the transmission line, two different sub-band frequencies are configured by switching on and off the switches.
