Abstract

This chapter analyzes a wideband flexible self-isolating MIMO antenna designed for Sub-6 GHz 5G and WLAN smartphone terminal applications. The chapter explores a specific design technique that involves the insertion of four octagonal rings between opposite sides of the main radiator. This technique aims to achieve a wider bandwidth for the antenna. The utilization of a flexible polyamide substrate for printing the radiators is a key focus in this chapter. This allows the antenna to operate across the entire Sub-6 GHz 5G and WLAN bands, making it suitable for smartphone terminal applications. Measurement data is presented in this chapter to facilitate comparison and validation of the proposed antenna prototype. By examining the measurement results, the performance and effectiveness of the antenna design can be assessed. Additionally, this chapter includes an analysis of the Specific Absorption Rate (SAR) for the conformability of the antenna design to smartphone terminal applications. SAR analysis is essential to ensure that the antenna operates within the safety limits for human exposure to electromagnetic radiation.
