Effect of Microstrip Line Dimensions on Bandwidth Enhancement of a Regular Microstrip Antenna

Microstrip antennas suffer from limited bandwidth. The dimension of the microstrip feed line has a profound effect in proper impedance matching. A good matching results in an enhancement of the bandwidth and return-loss. The present paper demonstrates the bandwidth enhancement of a microstrip antenna by using this method. The effect of feed dimension on the return loss and bandwidth is observed and presented in the paper. The simulations are conducted using ADS, and the results of the simulation are presented in the paper. Furthermore, with HFSS, more results are discussed. The simulated results will compare with the measured result. A close proximity justifies the results obtained by this method.
