Tiny antennas suit slimline cellular designs
Offered in left and right versions, Antenova's Integra and Inversa chip antennas are just 3.3 mm high for use in slimline 3G and 4G/LTE devices. The antennas perform efficiently with a small ground plane, even on PCBs as small as 65 mm. For boards smaller than 75 mm, Antenova supplies an active tuning circuit to overcome bandwidth reductions.
Integra and Inversa operate at different frequencies. Integra covers 791 to 960 MHz, 1710 to 2170 MHz, 2300 to 2400 MHz, and 2500 to 2600 MHz for European markets, while Inversa covers 698 to 798 MHz, 824 to 960 MHz, 1710 to 2170 MHz, 2300 to 2400 MHz, and 2500 to 2690MHz and is built for global markets. They are intended to work singly or in pairs for MIMO and diversity systems. Beam steering offers good isolation and cross-correlation and enables faster downloads in diversity applications.
