A BST (barium strontium titanate) Based Narrow Band Tunable Antenna For Improving Wireless Communication
North Carolina State University, 2004 - $18,000
Improving call quality and network coverage of cellular phone systems in an economically viable way is the one of the major concerns of service providers today. The quality of current wireless communication systems could be significantly improved by the use of a narrow band tunable antenna in cell phone handsets to increase network coverage, reduce the cost of materials used for manufacturing cell phones, and improve battery life. The Barium Strontium Titanate (BST) Antenna E-Team developed a low-cost method of fabricating a voltage tunable BST-based antenna.
Over the past three years, the Materials Science and Engineering Department at North Carolina State University has developed a thin film voltage controlled capacitor (varactor) using BST. The BST Antenna E-Team adapted the BST thin film technology to produce high quality integral varactors, which can be used to manufacture narrow band tunable antennas.
The BST-based antenna will help service providers increase their revenues and enable better wireless service for end-users, allowing them to differentiate their products in a highly competitive market.
