Handheld electronic device antennas
First Claim
1. A handheld electronic device, comprising:
- an antenna that handles signals at radio frequencies;
an electrical component that overlaps the antenna;
control circuitry; and
at least one resistor that is electrically connected between the electrical component and the control circuitry that isolates the electrical component from the antenna at the radio frequencies.

Abstract
A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables. A bracket with extending members may be crimped over the ferrules to ground the coaxial cables to the housing and other conductive elements in the ground plane. The ground plane may contain an antenna slot. A dock connector and flex circuit may overlap the slot in a way that does not affect the resonant frequency of the slot. Electrical components may be isolated from the antenna using isolation elements such as inductors and resistors.
