Details on the Verizon iPhone antenna death grip fix

by Justin Horn on Jan 13th, 2011 @ 5:16 pm

AntennaSys believes the new Verizon iPhone utilizes a new design to avoid the old, “non-existent”, I have no bars when I hold the phone in my left hand issue.

Spencer Webb from AntennaSys:

The SIM slot is gone, since it’s not a GSM phone.  That frees up a bunch of real estate on the PC Board.  Did Apple move the WiFi antenna (and probably also the GPS antenna) to the PC Board, under the rear glass?  I think so.

In their FCC filing, Apple describes the WiFi antenna as a “PIFA”.  This stands for Planar Inverted-F Antenna.  I would never describe the “frame” antenna using those terms.  So, this seems to support the theory.

Spencer also believes that with the extra space on the antenna band, from moving the WiFi and GPS antenna to the board, the band could now support two GSM antennas, to utilize ”antenna diversity”.

From the Wiki on antenna diversity:

Any one of several wireless diversity schemes that use two or more antennas to improve the quality and reliability of a wireless link.

This would allow the phone to switch between the two antennas, depending on which one has a stronger signal…the side that isn’t touching your greasy palms.
