The traditional bandwidth of ceramic patch antennas is relatively narrow. In order to achieve the broader bandwidth, a two-layer stacked antenna are commonly used. However, the higher cost and more weight could be an issue in some applications.
Since Unictron always accomplishes its goals from end-customer’s perspective, we invented the most perfect Castle Series for our valuable customers. The Castle ceramic patch is designed using a hollow structure, transforming two-layer ceramic into a single, monolithic, and small in size band new design, that grants Unictron with multiple international patents. The invention of Castle patch antenna enabling the capability of achieving multi-bands, which is practically unfeasible for single-layer antenna. It provides better signal quality than traditional double-stacked antennas, and the cost is highly competitive.
Common tracking and navigation systems such as GPS, GLONASS, Galileo, BeiDou ,or QZSS only use L1 band signals, and the precision of positioning accuracy is only about 5-10 meters. However, many lower frequency bands such as L2, L5, and L6 were becoming available to the commercial uses, which by using multi-frequency (ex. L1+L2 / L1+L5), it can eliminate errors by tracking multiple GNSS signals, reduce the effect of multipath and interference, and therefore achieving the highest accuracy possible.
Unictron is engaged in R&D and manufacturing of antenna-solutions, piezo ceramics, ultrasonic transducers and circuit protection products.
