Sarantel SL3105SP overmoduled iridium antenna

the SL3105 irdium antenna provides high performance in difficult iridium applications.

Product Description

Built on patented PowerHelix® fitering antenna technology, the SL3105 Iridium antenna provides high performance in difficult Iridium applications.

The SL3105 has improved low elevation gain, compared to the SL3101 antenna, through an improved antenna architecture. The SL3105 housing has improved ruggedness compared to the SL3101.

The SL3105 antenna is ideal in applications where:

• the device is handheld, body-worn, or otherwise surrounded by high-dielectric materials that would de-tune conventional antennas;

• the antenna is tightly integrated with other antennas, e.g., Iridium/GPS receivers

• there are tight constraints on the size of the device or the amount of space allocated to ground planes;

• the orientation of the device is random; or

• the antenna will be embedded in the device.

The SL3105 antenna is balanced, which isolates it from the device and enables the antenna to reject common mode noise resident on the device ground plane. The construction and materials of the antenna constrain its near-field to a very small volume, therefore materials near the antenna have negligible de-tuning effects and the antenna maintains its pattern and efficiency in the presence of dielectric loading. Additionally, due to the tightly constrained nearfield the antenna can operate close to human tissue and still pass SAR. As a dielectrically-loaded antenna, the SL3105 acts as its own filter,attenuating signals from cellular phone and ISM frequencies by as much as 30dB without external filter-ing.

The SL3105 antenna is offered with an SMA connection and is encapsulated in plastic.
