Molex debuts next generation MobliquA bandwidth enhancing antenna technologies

“Traditional passive antenna structures are based on meandered antenna patterns, with limitations on manufacturing tolerances and mechanical properties. The MobliquA technology enables simple mechanical and robust antenna designs that minimise efforts needed for iterative retuning during each build cycle,” explains Morten Christensen, RF research manager, Molex. “Compared to standard systems, such as L or F type antennas, this technology can provide improved impedance bandwidth improvements of 60-70% without increasing the antenna volume or compromising the radiation efficiency.”

Suitable for small mobile phones to tablet and laptop sized devices, the MobliquA technology offers a strong multi-use platform that supports both single and dual feed RF architectures within the same antenna structure. The dual feed configuration can provide at least 20dB isolation between the input ports, while maintaining the bandwidth enhancing features. The good isolation and bandwidth simplifies optimisation of antenna impedances to match different RF engines, which reduces current consumption and improves power transfer efficiency.

The MobliquA technology provides a high degree of immunity towards insertion of metal objects into the antenna volume. Additionally, it enables utilisation of RF decoupled or grounded parts, such as a grounded connector housing, as an integrated component of the antenna system. Furthermore, the technology provides excellent ESD protection of the front end due to its unique feeding techniques combined with a direct grounding of the antenna elements.

MobliquA bandwidth enhancing antenna technology is now available for new designs and has already been chosen by a leading tier-one mobile phone manufacturer for upcoming product launches.
