Patch Antenna Performs with Two Frequency Bands
April 23, 2008 |Estimated reading time: Less than a minute
FAIRVIEW, Pa. Spectrum Control Inc. launched a single-element patch antenna that receives and/or transmits two frequency bands in one 45-mm package. This dual-frequency patch antenna is designed for space and cost savings compared to using two single-frequency patch antennae.
The patch antennae were developed for global positioning systems (GPS) using either Globalstar: telephone & low-speed data communications or Iridium: worldwide voice & data communications in handheld satellite phones.
To perform at the required frequencies, Spectrum's dual-frequency patch antenna is a 45-mm antenna element mounted on a 63-mm ground plane. The frequencies available are 1575MHz (GPS) to 1615MHz (Globalstar) and 1575MHz (GPS) to 1621MHz (Iridium). The components are flat ceramic, low-profile antennae with no interference issues 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.
