Abstract

Enhanced array performance can be achieved by increasing number of array elements but at the cost of increased side lobe levels. These sidelobes can be supressed by integrating graphene oxide based electromagnetic absorbers along with antenna array on a single substrate. Absorbers can effectively reduce the side lobe levels of array by absorbing their interelement coupling waves, the ambient temperature of array however increases as the absorbed side lobes dissipate into heat which is not desirable. Temperature compensation technique is hence proposed whereby the temperature shift is controlled by utilizing heat sink mounted absorber for improving the performance of antenna array.
