Abstract
A testing apparatus for testing mobile telephones includes an antenna coupler, a holder and a testing device. The antenna coupler includes a printed circuit board upon one side of which is formed a slot antenna operative in a first frequency range and a dipole antenna operative in a second frequency range. The holder secures a mobile telephone under test in proximity to the antenna coupler. A coupler formed on a second side of the printed circuit board selectively supplies signals received by one of the antenna elements to the testing device. The testing device measures transmission and reception characteristics of the mobile telephone under test, including transmission phase error, frequency error, power and spectrum, and bit error rate.
