We proposed a low profile surface wave antenna with directional beam using microstrip element . Proposed antenna can design at the desired resonance frequency by changing microstrip length L and width W . In addition , we proposed process of design the desired resonance frequency by using some formulas . Also , we designed the antenna having the resonance frequency of 10 GHz by using proposed method . Furthermore , we made simulation and measurement in S11 characteristics and radiation pattern . As a result , we can get bi directional beam in proposed antenna.
