The height of the antenna directly affects the bandwidth of the low frequencies, the higher the height the better the bandwidth. The metal bezel, if the bezel is metal, also has a particularly large effect on the antenna.

FIG. 6 illustrates the isolation between the primary and secondary antennas of the present invention;
specifically, the antenna spatial isolation is to keep a certain physical spatial distance (angle) between a transmitting antenna of an interfering system and a receiving antenna of an interfered system, so that the level intensity of an electric wave of the transmitting antenna reaching the receiving antenna after spatial attenuation is smaller than the requirement of the inter-system isolation. A certain distance can be kept between the antennas to realize spatial isolation, and spacers can be added between the antennas of different systems to increase the isolation between the antennas; it can be seen from the diagram that the isolation of the ratio of the signal transmitted by the main antenna 2 and the signal power received by the auxiliary antenna 4 is less than-15 dB, which can satisfy the high-efficiency WiFi frequency band.
