Multi-Band Antennas for 4G, 5G FR1 and Wi-Fi 6E/7 Bands in Smartwatch Devices
This article introduces an antenna design for smartwatch applications, with an overall size is 45 × 45 × 5.4 mm3. All antenna elements adopt the IFA (Inverted-F antennas) structures. The application bands include Global Positioning System (GPS), Wi-Fi 6E/7 with 2.4 GHz, 5.2 GHz, 5.8 GHz and 6 GHz bands, 4G LTE (Long Term Evolution) with B2 and B4, 5G n41, n77, n78, n79 bands, covering all Wi-Fi 6E/7 and the mainly bands of 5G FR1 bands. Additionally, this design also reserves a frequency band in the 6G mid-high band (6–9 GHz), ensures that design can be suitable for next generation of wireless systems. Furthermore, the antenna element designed for switching B2 and B4 bands to reduce the occupied space of the element. The design with five antennas and good performances can be applied to the bands of 4G, 5G FR1, and Wi-Fi 6E/7 systems in smartwatch applications.
