Chip Antenna
The Johanson Technology ceramic chip antenna is a passive, surface mount component, based
on Low Temperature Co-fired Ceramic (LTCC) technology. This antenna exhibits linear
polarization and provides a near omni-directional radiation pattern. It is matched to 50 ohm
impedance and is well suited for integration to the LSR TiWi5 radio module.
The chip antenna is used external to the TiWi5 module as part of an overall solution for the LSR
TiWi5 radio module.
