Abstract—The paper provides insight into the effect of electromagnetic band gap structures, defective ground structures and nano film deposition on microstrip antenna array. The modified microstrip antenna array provides overall bandwidth and reduced mutual coupling of 254.7 %, –31.29, –30.78 and –33.20 dB respectively. In addition a high gain of 15.03 dB is also obtained. The modified microstrip antenna array is also producing good radiation characteristics in the form of reduced back lobe radiation. On the other hand the conventional microstrip antenna array produces bandwidth, gain and mutual coupling of 4.89 %, 6.81, –16.95, –14.22 and –17.30 dB respectively. The fundamental resonant frequency of conventional microstrip antenna array is 5.53 GHz. FR-4 glass epoxy is employed as the dielectric substrate. The microstrip antenna arrays are designed using Mentor Graphics IE3D software.
 
Index Terms—corporate feeding technique, gain, microstrip antenna array, mutual coupling, radiation pattern, return loss.
