Small balanced antennas for Bluetooth applications

Abstract

This paper presents a low cost and high quality small planar antenna design for the Texas Instruments 2.4 GHz Bluetooth low energy and Proprietary System-on-Chip application. It discusses all important theoretical aspects of applicable balanced antennas, describes the process of computer aided design and simulations, and presents experimental verifications of simulated results. All simulation results for the antenna voltage standing wave ratio (VSWR) are verified by measurements and they are below 2 in the complete 2.4-2.485 GHz frequency band.
