ABSTRACT:
Antennas, handheld electronic devices containing antennas, and methods for using antennas and handheld electronic devices are provided. A handheld device may have a conductive case. The antenna can be formed as part of a button such as a pushbutton. The pushbutton may protrude from the conductive case sufficiently to allow good transmission and reception of wireless signals. The protruding antenna contains a radiating element, while the conductive case serves as a ground. The radiating element may be formed from a low-profile antenna structure such as a planar antenna structure formed on a circuit board substrate. The pushbutton may be used to control operation of the handheld electronic device. With one suitable arrangement, actuation of the pushbutton antenna causes the antenna to protrude from the case and turns on transceiver circuitry in the handheld device.
