Spectrum Control Offers Dual-Frequency Patch Antenna

Spectrum Control, Inc., of Fairview, Pennsylvania, has designed a new single-element patch antenna that can receive and/or transmit two frequency bands — GPS and satellite communications — in one package.

The new antennas were developed for GPS applications using either Globalstar, for telephone and low-speed data communications, or Iridium’s voice and data communications. The frequencies cover 1575MHz (GPS) to 1615MHz (Globalstar) and 1575MHz (GPS) to 1621MHz (Iridium).

The dual-frequency design contains a 45-millimeter antenna element that is mounted on a 63-millimeter ground plane. The flat ceramic, low profile units are available in RoHS-compliant versions in accordance with the European Union’s 2006 Restriction of Hazardous Substances directive. According to Spectrum Control, custom designs can be created that to meet specific mechanical needs.

Unit pricing ranges from $3 to $8 depending on quantities required.
