Abstract

This letter proposes a frequency-diverse multitarget wireless sensing system for integrated sensing and communication (ISAC) applications. A coupled-patch antenna (CPA) with frequency-dependent beam scanning capability is employed as the key component for multitarget localization and respiration detection. Owing to the high scanning rate of 25.8° per 1% bandwidth, the designed CPA is able to continuously scan an angle range of 93° across broadside as frequency varies from 3.26 GHz to 3.38 GHz, which well fits the ISAC application in sub-6 GHz frequency. Four examples are given to demonstrate the benefit of high-scanning-rate CPA for multitarget localization, respiration detection, and surrounding interference mitigation.
