Unictron’s Castle Patch Antennas for Enhanced Positioning Accuracy

A hiker holding a GPS unit while navigating a mountain region; Unictron's Castle Patch Antenna is uniquely suited for GPS and other positioning devices; find out more at Sourcengine.

Based in Taipei, Taiwan, Unictron Technology Corp. is a leading microelectronics supplier that specializes in developing antennas and piezoelectric ceramics. Founded in 1988, the company has extensive experience developing cutting-edge electronic components. The company brought the full measure of its expertise to bear when designing its Castle Patch antennas.

Thanks to their unique form factor, the series lets OEMs create devices with world-class global positioning accuracy, improves performance, and reduces narrowband interference.

Specifications

Since BeiDou, Galileo, GPS, QZSS, and GLONASS utilize the L1 frequency band (1575.42 MHz) to provide satellite navigation services, it has become a worldwide standard in the last two decades. As technological development has continued, GPS and GLONASS integrated the L2 band (1227.5 MHz) into their offerings. As such, component manufacturers created stacked patch dual band antennas that boast greatly improved location precision and capability.

Unictron has pushed global positioning technology even further with its groundbreaking Castle Patch antenna chip and components.

The firm modified its monolithic design to create a hollow portion in the ceramic material that effectually creates a virtual second body. Consequently, its chips offer GNSS dual band locational accuracy within 30cm as opposed to the typical 5m range. Unictron also offers Castle Patch antennas that use the safety-of-life L5 band (1176.45 MHz) to perform signal acquisition in just 200 milliseconds, even in multipath environments.

The manufacturer’s cutting-edge Castle Patch antennas provide the enhanced signal reception of dual band technology in a compact package. The firm’s castle patch components measure 40mm x 40mm x 6mm, 2mm slimmer than stacked patch antennas. As a result, OEMs will have more space to work with when using Unictron’s positioning chips in their products.

The firm’s innovative design also affords wider bandwidth access, meaning the components can utilize BeiDou, GPS, and GLONASS as signal sources at the same time.

Because of their robust capability and multifaceted functionality, Unictron’s Castle Patch Antennas can be used in the automotive, agricultural, consumer electronics, and marine sectors.

For instance, the firm’s PD40D9 Ceramic Patch Antenna is a high-performance telematics offering that is ideal for use in multiple fields. Since it uses L1 and L5 frequency bands, it offers ultra-high positioning accuracy, a strong axial ratio, and superior radiation efficiency. The chip also has a robust temperature range of -40°C to 85°C.

OEMs designing innovative fleet tracking devices, farming tools, or marine transportation equipment would be well-served by utilizing the PD40D9.

Unictron’s AA088 GNSS Ceramic Chip Antenna is a fantastic option for manufacturers looking to save costs without compromising quality. The component covers 1560-1606 MHz band frequencies to provide excellent positioning performance in a low profile SMT package.

The AA088 is also compatible with GPS, BeiDou, GLONASS, and Galileo services, which means it has high locational accuracy in multiple geographic regions. OEMs interested in producing world-class standalone global navigation devices and handsets should add it to their inventories.
