Meanwhile, the gap between the lower main antenna 120 and the first auxiliary antenna 150 can reduce the coupling between the lower main antenna 120 and the first auxiliary antenna 150, which is beneficial to increasing the isolation between the lower main antenna 120 and the first auxiliary antenna 150 (the isolation is an index representing the mutual influence between adjacent antennas, and the higher the isolation of the antennas is, the smaller the mutual influence between the antennas is).
In one embodiment, the first secondary antenna 150 is designed to be rib-to-ground (rib-to-ground refers to the grounding structure of the IFA/PIFA antenna) near the break of the headphone jack 170, increasing the isolation between the lower primary antenna 120 and the first secondary antenna 150.
The mobile device, wherein the upper main antenna 110 and the second auxiliary antenna 130 are closely arranged, the line loss from the PA output port to the input ports of the two cellular antennas is small, the second auxiliary antenna 130 is a WiFi-2.4G Chain1 and M + H antenna common antenna, and can cover the frequency band of WiFi-2.4G Chain1(WiFi-2.4GMIMO antenna), and the arrangement and design can reduce the number of antennas, which is very beneficial to the tight mobile phone space.
The third antenna 140 and the fourth antenna 160 are arranged close to each other, so that for the WiFi-5G Chain0(WiFi-5G MIMO antenna) in the third antenna 140 and the WiFi-5G Chain1(WiFi-5G MIMO antenna) in the fourth antenna 160, the insertion loss between the PA output port (PA output port of the power amplifier) and the antenna input port can be reduced; the WiFi-5G Chain0(WiFi-5G MIMO antenna) in the third antenna 140 and the WiFi-5G Chain1(WiFi-5G MIMO antenna) in the fourth antenna 160 are orthogonal to each other, so that the isolation between the WiFi-5G Chain0(WiFi-5G MIMO antenna) and the WiFi-5G Chain1(WiFi-5G MIMO antenna) can be improved, the polarization of the two antennas is orthogonal, and the polarization mismatch between the WiFi-5G MIMO antenna and the router antenna at a certain angle can be avoided.
