Developement of 4-Ports Mimo Cp Antennas for Radar Applications

Abstract

This paper introduces a printed four-port MIMO antenna with advantages such as compact size, excellent MIMO diversity performance, and simple geometry for radar applications at 10 GHz. It is small size makes it suitable for integrating various telecommunication devices for multiple applications, with a prototype measuring 32 mm × 32 mm × 4.3 mm. The mutual coupling between the individual elements significantly im-pacts the MIMO system's diversity properties, and an effective technique of orthogonally positioning the antenna elements to each other increases their isolation resulting in superior MIMO diversity performance. It is evaluated through S-parameters and MIMO diversity parameters to ensure its suitability for future radar applications. It is validated through measurements, and the results showed a good match between simulated and measured results. The different diversity parameters such as (Envelope Correlation Coefficient (ECC), Diversity Gain (DG), Channel Capacity Loss (CCL), Multiplexing Efficiency (ME), Total Active Reflection Coefficient (TARC) are simulated and measured. It is found that all values are within the standard norms which indicates the availability for MIMO radar applications. © 2024 IEEE.
