Abstract :
Microstrip antenna consists of a radiating patch on one side of dielectric substrate which has a ground plane on the other side. The antenna element it self may be square, rectangular, circular, triangular etc and may have more than one feed. An experimental study of dual band characteristics of single layer rectangular microstrip antenna is presented. For feeding of the antenna direct microstrip coupling with proper matching transformer has been used. The optimized notch dimension has been taken for two resonant frequencies. The resonance frequency changes with the variation in the length and width of the notch. The VSWR is measured with the help of network analyzer.
