Abstract

In this paper, a coplanar capacitive coupled suspended microstrip antenna with reduced air gap (compact) for wireless applications is presented. Suspended microstrip antennas offer wide bandwidth due to the reduced effective dielectric constant and surface waves. However, air gap in the suspended configuration is the prime constraint in compact applications. Therefore, in this paper it is demonstrated that the air gap can be significantly reduced by utilizing the previously reported approaches and modifying them would result in significant reduction compared to the results reported earlier for the similar antenna geometries. The designs presented here exhibit the fractional impedance bandwidth of nearly 25% for all cases studied in the frequency range of 2-10 GHz.
