摘要：In this paper, the tuning characteristic of a rectangular microstrip patch antenna has been studied. It has been shown, how the variation of length of the slot embedded in the ground plane results in shifting of resonant frequency. The antenna mentioned in this paper operates at two resonant frequencies. By modifying the length of the embedded slot, the ratio of the higher resonant frequency to the lower frequency can be varied from 2.03 to 1.In actual case it has been found that one of the resonant frequency remains fixed irrespective of the slot length. If the ratio of this fixed frequency to the tunable resonant frequency is considered, then the ratio can be varied from 2.03 to 0.7 by varying the slot length.
