Spectrum Control Develops Dual Frequency Patch Antenna

Spectrum Control, Inc. has designed a new 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 new 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.

Spectrum Control Develops Dual Frequency Patch AntennaTo perform at the required frequencies, Spectrum’s new dual frequency patch antenna is a 45mm antenna element that is mounted on a 63mm ground plane. The frequencies available are 1575MHz (GPS) to 1615MHz (Globalstar) and 1575MHz (GPS) to 1621MHz (Iridium). These dual frequency patch antennas are a flat ceramic, low profile antenna with no interference issues to design around and are available in RoHS compliant versions. Custom designs can be created that are modified to meet a company’s mechanical needs while optimizing performance.

Spectrum Control’s dual frequency patch antennas have pricing ranging from $3.00 to $8.00 depending quantities required.
