Taoglas has introduced a new antenna design that will increase antenna performance in shorter ground planes, allowing engineers to create new small IoT devices that would otherwise not be able to meet certain stringent carrier certification requirements.
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 resulting in the devices needing to be larger than required for the application they serve.
Taoglas said it has addressed this challenge through a new technique that alters the electrical delay in the ground plane to improve efficiency at the lower frequencies typically used in cellular applications. This 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 engineer in terms of antenna integration.
Because Taoglas Boost is implemented in a customer device, it results in up to 2 dB of antenna efficiency improvement. Extra antenna gain improves any system-level gain, but this improvement is useful to meet over-the-air requirements for size-constrained devices found in M2M and IoT applications.
Taoglas is showcasing the antenna technology at this week’s Mobile World Congress Americas, taking place in Los Angeles.
