ANTENOVA Pharaoh SMD antenna P/N SR4L073) is designed for small pcbs, and covers all 4G frequencies: 698 – 824MHz, 824-960MHz, 1710-2170MHz, 2300-2400MHz and 2500-2690MHz. Product’s small ground requirement offers designers a huge advantage in designs on a small circuit board, such as miniature pet trackers, wearables or OBD-II designs. Device was tested with evaluation boards of 50 x 40mm and 60 x 40mm and its performance-to-footprint ratio out-ranked competing 4G antennas for small circuit boards. They typically require a minimum 60 x 40mm of space, utilise large and costly band switching networks and display lower levels of efficiency. Product’s performance on small PCBs is above the level required to pass PTCRB tests for cellular networks.
