Taoglas unveils what it calls a revolutionary breakthrough in antenna design that will deliver significantly increased antenna performance. This innovation is particularly suited to designs with shorter ground planes.
Due to the migration to 4G cellular networks, additional frequency bands are used by network providers to increase service level speeds and throughput. Many IoT devices require that antennas be able to send and receive efficiently at all bands to be globally compliant, without the need to change antennas based on region. Devices may also require 2G/3G fallback. Traditionally this is achieved by increasing the ground-plane length of the board the antenna is mounted on. As a result, many devices are larger than is required—or practical—for the application they serve.
Taoglas Boost handles the challenge with a new technique to alter the electrical delay in the ground plane to improve efficiency at the lower frequencies (600 to 1,000 MHz) typically used for cellular applications. The modification can be implemented in the “keep-out” area of the antenna, the area on the host circuit board reserved for antenna placement, causing minimal impact to the designer in terms of antenna integration.
A tuning feature is integrated into the design to allow for quick optimization as Taoglas Boost is implemented in a user device. The result is up to 2 dB of antenna efficiency improvement on the same ground plane length compared to traditional technology. Extra antenna gain improves any system-level gain, but this improvement can be particularly useful to meeting over-the-air (OTA) requirements for size-constrained devices commonly found in M2M and IoT applications. This technology can be implemented with any onboard antenna. For more information, visit Taoglas Boost.
