A compact two elements MIMO antenna for 5G communication
By Technical Paper Link - 18 Mar, 2022 - Comments: 0

Abstract: "This study presents a simple, miniaturized, and low-profile multiple-input multiple-output (MIMO) antenna operating at 29 GHz with reduced mutual coupling between the antenna elements for futuristic 5G communication. The proposed design employs two radiating elements with slits in the radiators to produce high isolation among the antenna radiators. The MIMO antenna maintains a compa... » read more

RF To mmWave Design For Systems
By Cadence - 23 Feb, 2022 - Comments: 0

RF-enabled next-generation communication systems and connected devices are differentiated by their performance, size, and cost. Traditionally, custom proprietary IC designs, leveraging the latest advanced-node technology, were developed to meet these product requirements. Increasingly these challenges are being met by moving beyond single IC solutions. Today’s electronic systems often integra... » read more
