Apple iPad 3G: Metal case bottomAt the bottom of the Apple iPad 3G's metal case, we find one of the Wi-Fi antennas, the speaker assembly, data port, and the contacts for the home button. Along the left side, is the microSIM card slot. The black connector strip that runs down the center of the battery assembly, attaches the components at the bottom of the device to the main logic board. Under the connector, you also find the Wi-Fi and Bluetooth communication cards. A second antenna is mounted behind the battery assembly.
