Dual Band Microstrip 2×8 Array Antenna At Green Flexible RF

5G empowers a novel network that is envisioned to unite all the appliances, machines and gadgets effectively. 5G introduces wide bandwidth with the extension of additional frequency spectrum resources. The 5G network is capable of working both in lower bands like S-band and C-bands and also works in millimetre wave spectrum including Ka-band that helps achieve higher data rate, gain, efficiency and reduced delay. High performance, wideband high gain, compact size and low profile millimetre wave antennas are required for 5G enabled applications to achieve interference free communication. This article presents a microstrip array antenna for millimetre wave applications that resonates in dual bands at green flexible radio frequency range. The antenna array uses parallel feeding technique. The artistic slots introduced in the patches, round and opposite corner fillets result in dual frequency resonance at 57GHz and 60GHz. The proposed small array design with size of 2 × 8 and defected ground results in better gain, directivity, efficiency which is suitable for 5G communication.
