Design, fabrication and measurement of an encapsulated inverted F dual band antenna for the gathering of data on seals at sea using SMS over a GSM system

In this paper a novel encapsulated dual band planar inverted F antenna is presented designed for the specific application of gathering data on seals at sea. A mobile phone module with the above antenna is encased in epoxy resin and affixed to a seal for transmission of sensor data via the short message service over GSM in both European frequency bands. Results are presented for a prototype both in anechoic facilities and affixed to a seal at sea. Finite element software is used for optimisation.
