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).
