Spectrum Control Designs Single Element Patch Antenna

Spectrum Control has designed a single element patch antenna that can receive and/or transmit two frequency bands in one 45mm package. This dual frequency patch antenna provides a space and cost savings compared to using two, single frequency patch antennas. These patch antennas were developed for GPS (global positioning systems) using either Globalstar: telephone & low-speed data communications or Iridium: worldwide voice & data communications using handheld satellite phones. Mounted on 63 mm ground plane, the single element patch antenna can receive and/or transmit 2 different frequency bands from its 45 mm package. It is developed for GPS using frequencies from 1,575-1,615 MHz (Globalstar) and 1,575-1,621 MHz (Iridium). Also available in RoHS-compliant versions, flat ceramic antenna has low profile and no interference issues to complicate design. The dual frequency patch antennas have pricing ranging from $3.00 to $8.00 depending quantities required.
