Abstract: Now a days 4G communication requires high gain and easy integrated array circuits. Various communication systems require single radiating element operating in wide band. Microstrip antenna has all these advantages but it has some limitations, like low gain, low bandwidth and surface wave propagation. Use of negative inductor, negative capacitor or negative resistor overcomes this disadvantage of Microstrip antenna. In this paper, we will see how the bandwidth of a Microstrip antenna is enhanced with the use of negative inductor, negative capacitor and negative resistor separately. A comparison will be made based on the results obtained so that we can find out that out of negative inductor, negative capacitor and negative resistor which one provides the maximum bandwidth enhancement for a Microstrip Antenna.
