The PCS.68.A is a low-profile, surface-mount (SMD) wideband PCB antenna designed for 5G/4G applications. It operates across a wide frequency spectrum from 600 MHz to 6000 MHz, covering all sub-6GHz 5G FR1 bands and providing fallback support for 3G/2G. With a compact footprint of 42 x 10 mm and a height of just 1.5 mm, this high-efficiency antenna is designed for direct mounting on a device's main PCB via standard pick-and-place machinery. The patent-pending design delivers high radiation efficiency across its operating bands, making it ideal for space-constrained IoT applications such as autonomous vehicles, smart metering, connected health devices, and payment terminals.
