Abstract
Apparatus and methods for the design and dynamic tuning of antenna circuitry for use across multiple radio frequency bands in wireless communication devices is disclosed herein. An antenna apparatus includes antenna tuning control, antenna tuning circuitry, and a set of one or more physical antennas. The antenna tuning controller includes a combination of baseband and front-end hardware and software. The antenna circuitry collectively includes antenna tuning circuitry and the set of one or more physical antennas. Based on a set of radio frequency bands and on communication channel conditions, the antenna tuning controller determines an optimal antenna tuning configuration and provides appropriate parameters to the antenna tuning circuitry. The antenna apparatus configures and optimizes the tuning of the antenna circuitry for a future time period, which can be a next time slot. The antenna tuning controller utilizes a cost/gain function to calculate the optimal antenna tuning configuration.
