Transparent and flexible coplanar antenna for 5G mobile communication

Abstract

Over the few decades wireless mobile communication technology has developed tremendously although the inception of this is not so ancient. Recently the electronic device fabrication technologies are moving towards transparency and flexibility. That’s why for accelerating the journey towards communication technical revolution, researchers are now mostly focused on designing transparent and flexible antenna. As we are moving to 5th generation (5G) wireless mobile communication, we suppose transparent and flexible antenna would enhance its possibility. Now we are proposing an antenna that would be visibly transparent using AgHT-8 as conductive material. We mostly focused on studying the characteristics of different materials to reach our goal and used CST microwave studio for simulating possible antenna design and analyzing return loss, radiation pattern, efficiency and directivity of them. Then we looked for the perfect material like transparent conductive oxide (TCO) like Indium Tin Oxide (ITO). We became successful in designing an antenna using AgHT-8 material over Polyethylene Terephthalate (PET) substrate operating in 28GHz with maximum transparency and flexibility possible enabling 5G mobile communication. Performance tuning of the Y- shaped antenna changing the angle between two arms of Yshaped antenna and effect of adding lumped element (resistor) is discussed thoroughly.
