Performance Optimization of Microstrip Antenna with Different Slot Configurations and Various Dielectric Materials

摘要

The probe-fed patch antennas were proposed by changing the parameters such as dielectric materials and dimensions of patch for detail investigation of changes in output characteristics.Four rectangular slots were introduced separately for optimizing the antenna design and characteristics.This study illustrated the changes of output characteristics of an antenna with respect to the number of introduced slots on the radiating patch in addition to the effect of various dielectric materials on antenna performances.The antenna performances were analyzed by plotting the observation of various dielectric materials.The changes of antenna characteristics were also observed by introducing four numbers of slots on each edge of the patch to improve radiation characteristics with a wider impedance bandwidth.
