| Summary: | The paper throws light on the potentiality of electromagnetic band gap structure and defective ground structure in ameliorating
the performance of four element microstrip antenna array. Plus shape patch type electromagnetic band gap structure and rotated
dumb bell defective ground structure are employed. The proposed antenna array has bandwidth and gain equal to 54.54 % and 12.77
dB respectively. Virtual size reduction of 26.58 % is also produced. The interference level is improved with reduction in mutual
coupling value from -17.83dB to -25.13 dB respectively. Moreover, the proposed microstrip antenna array is also yielding appreciable
reduction in back lobe radiation. The dielectric substrate employed is FR-4 glass epoxy. The microstrip antenna arrays are designed
using Mentor Graphics IE3D software and measured results are obtained using vector network analyzer. |
