Abstract

Increased spectrum coverage and data rates required by 3G/4G/LTE mobile wireless devices are dictating the need for active antenna systems. Advancements in technology and design techniques have enabled new and innovative solutions for implementing antenna tuning and impedance matching. High Quality (Q) factor Digitally Tunable Capacitors (DTCs), tuning switches and reconfigurable tuners allow for dynamic adjustment of an antenna´s electrical characteristics, and extended low-band coverage through the implementation of aperture tuning and tunable matching networks. This paper discusses the product capabilities and design options that result in improved antenna operating bandwidth.
