| Abstract | ||
| Simple Cavity Model (SCM) was used to solve the problems related to the measurement of the characteristics of microstrip antennas MSAs, where the electric and magnetic fields were calculated . The programming of the SCM equations was done using MATLAB language. The antenna parameters such as: (input impedance, return loss ,bandwidth, resonance frequency and radiation patterns for both 〖TM〗_11 mode and 〖TM〗_21 mode) were computed and plotted. From which the bandwidth and directivity of the circular microstrip antennas have been determined. We found the increasing in the bandwidth value was obtained from increasing the thickness of the dielectric substrate in the CMSA and decreasing the dielectric constant. | ||
