This article demonstrates the alleviation of mutual coupling of a simple and low-cost four-element microstrip array antenna by loading I-shaped slot-type electromagnetic band gap structure in the ground plane. FR-4 glass epoxy is used as dielectric substrate. Moreover. the proposed array antenna shows a better performance in terms of multi-band resonance. https://www.markbroyard.com/limited-offer-annamaet-senior-rejuvenate-for-sale-flash-buy/
