In this paper a novel structure of Microstrip Yagi-Uda antenna is introduced to use in two frequency bands of 0.915GHz and 2.440GHz. FR4 with dimension of and height of 1.6 mm is used as substrate. A prototype of the antenna is fabricated to check its operation. Comparison of the simulation and measurement results confirms the operation of antenna. Return loss of the antenna at the operation frequencies is more than 20dB. Gain of the antenna at 0.915 GHz and 2.440 GHz is respectively 6.15 dB and 9.55 dB. Appropriate return loss, high gain at the operation frequencies, desired F/B ratio, low cost and compact size made this antenna suitable for various communication applications.
