  • Dual band antenna pair with high isolation
    Patent number: 9437935
    Abstract: A dual band printed antenna pair operates simultaneously at both WLAN frequency bands (2.4 GHz/5 GHz). The antenna pair provides high isolation between both antennas while having an efficient over the air performance. The antenna pair achieve greater than 20 dB isolation at 2.4 GHz and 5 GHz band, while having antennas positioned in close proximity. The high isolation is accomplished using an orthogonal antenna configuration (exploiting orthogonal polarization) and a parasitic element to further enhance isolation at 2.4 GHz. The antenna pair and parasitic element are printed on a Printed Circuit Board (PCB) adding relatively little cost to the Radio Frequency (RF) interface. The PCB is then fixed on top of a metal chassis with the antenna keep out area overhanging a corner of the metal chassis to enhance performance.
