Attached are some images of two antennas that were removed from wi-fi type devices, they are both for 2.4ghz devices. The J one looks like a Jpole to me, (obviously), the I one looks like a whip with ground aerials on the reverse side, can someone properly characterize the two types of antennas used here? I'm a bit rough in the antenna department, are they both quarter wave?
