Abstract :
In this paper, we consider how patch width W and length L effect the center frequency and return loss by electromagnetic field simulator. Then, we find optimum value of W and L at 20 GHz, when slot length S is 1.0 mm and displacement between center of patch and slot D is 0 mm. On the basis of the result, we modify the design formula of patch width W.
