Abstract

Increased spectrum coverage by mobile wireless devices is dictating the need for active antenna systems. Silicon-on-Sapphire (SOS)-based Digitally Tunable Capacitors (DTCs) and switches enable tunable matching networks and dynamic adjustment of antenna electrical characteristics. Advancements in technology and design techniques have enabled improvements in DTC electrical performance. This paper addresses advancements in DTC and switch capabilities and the resulting improvements in antenna operating bandwidth.
