The XPOL-2-5G-US is Poyntings third generation inchV3inch of this very popular Cross Polarised (XPOL), cellular band, 2X2 MIMO antenna. The antenna enclosure effectively looks the same as the second generation inchV2inch but has been completely redesigned on the inside. We have used advanced metamaterial technology, making use of Artificial Magnetic Conductors (AMC) and new registered/patent pending radiator configuration, which is proving to yield exceptional improvements in bandwidth and gain. Radiation patterns of this antenna are exceptionally well controlled, further adding to the performance of the antenna. The XPOL-2-5G-US antenna includes the 617 to 894 MHz band and the newer 3400 3800 MHz bands, which were not previously covered by our V2 and is suitable for 2G, 3G, 4G & 5G. This antenna performs exceptionally well in the following frequency bands: 617 894 MHz, 1710 2170 MHz, 2300 2700 MHz & 3400 3800 MHz. In addition to the new bands, the gain in the 1700 MHz and 2.7 GHz is around 3 dB higher than the inchV2inch over the same frequency bands! Our inchV2inch antenna already outperformed most competitors over these bands, so this substantial improvement in gain shows the benefits of the new advanced materials and novel radiator design.
