How does the antenna design on the iPhone 6 work?
I noticed that the housing of the iphone 6 consists of three parts. one part is the big middle part where the logo is, which includes the two metal parts enclosed by the plastic stipes (where the camera and flash are i.e.) and then the two metal bands one on top and one on the bottom (where headphone, lightning and speaker grill is).
These metal bands are not connected to the main "chassis", they are only attached with molded plastic and are therefore electrically isolated.
My question is, since internal parts are connected to these metal bands and the logic board also has a kind of connection to it, could it be that these bands are the antennas themselves ? and (i suspect so) do the have to be isolated from the main "chassis"?
the other explaination for this design could be that it is cheaper to build that way and that the "gaps" in the housing (the plastic stripes) are enough to allow antennas on the inside to work.
does anybody know more about this ?
Thank you very much,
Is this a good question?
