Design of multiband array antenna in MM wave for 5G applications [articol]

Abstract

The Present works brings a new approach in designing a multiband 5G based on microstrip antenna array using EBG structure. A 5*2 matrix array has been apprehended on Rogers 5880 dielectric substrate. The design is to improve the return loss characteristics of the radiating patch and having multiband operation. The defected ground structure is analyzed and further upgradation in performance metrics like directivity has been adapted with a suitable EBG structure which is used in the radiating structure. Numerous parameters like radiation pattern and VSWR have been premeditated in detail. The introduction of EBG layer, directivity is observed to improve to 8.4dBi and 12dBi at 28GHz and 37.5GHz. The overall return loss of the antenna array is found to be 15 dB and 16 dB at 28 GHz, 37.51 GHz respectively.
