The iPhone 4 Antenna Unravelled
Posted: 13-Jul-2010 [Source: Forbes]

[Andrew Seybold offers background info on antenna placement in handsets and the problems encountered in getting good reception.]

By Andrew Seybold (Forbes) -- "When it was reported that the new iPhone 4 was making use of the metal band around the phone for the “antenna” and if you held the iPhone wrong the signal disappeared or got weaker, there as a flurry of articles about this method of antenna placement. Soon after, Apple announced that part of the problem was that their software formula for determining signal strength—i.e., showing how many “bars” of signal was available—was in error and that in reality the signal strength was really lower than that being shown."
