In this paper, Co-Planar Wave (CPW) feed micro-strip antennas are designed to form dual frequency by inserting single stub. Bandwidths of the micro-strip printed antennas for both upper and lower frequencies are represented in this paper by considering the simulated and experimental results. For each size of T-matching network and each permittivity values are varied and effects of these variations are analyzed. The presented printed antennas in literature which have the same shape and the same feeding types are compared and results are presented.
