摘要： 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.

摘要： A compact tunable antenna for a handheld electronic device and methods for calibrating and using compact tunable antennas are provided. The antenna can have multiple ports. Each port can have an associated feed and ground. The antenna design can be implemented with a small footprint while covering a large bandwidth. The antenna can have a radiating element formed from a conductive structure such as a patch or helix. The antenna can be shaped to accommodate buttons and other components in the handheld device. The antenna may be connected to a printed circuit board in the handheld device using springs, pogo pins, and other suitable connecting structures. Radio-frequency switches and passive components such as duplexers and diplexers may be used to couple radio-frequency transceiver circuitry to the different feeds of the antenna. Antenna efficiency can be enhanced by avoiding the use of capacitive loading for antenna tuning.
