摘要:
A simple internal or partly internal antenna system for optimizing the radiation pattern from hand held wireless communications devices HHWCD such as hand-held data devices and cellular telephones is disclosed. The antenna system consists of an essentially internal or partly internal asymmetrical dipole with quarter-wave resonator section and radiating planar section, in conjunction with a planar parasitic director element. The radiating planar section may be the ground traces of the HHWCDs printed wiring board PWB. The antenna system provides for single or multiple frequency band operation.

Systems and methods for providing antennas for transmission and reception of radio frequency communications. More particularly, implementations of the present invention relate to a device and method for positioning antennas on surfaces encasing or surrounding an electronic device such as the rear of a flat panel display television or a laptop computer, smartphone, or pad computer, or on plates and components which removably engage with such devices.
摘要:
Compact portable wireless devices and antennas for compact portable wireless devices are provided. The compact portable wireless device may be part of a piece of sports equipment. A compact portable wireless device may include a transceiver module that is used in communicating with equipment such as a handheld electronic device. An antenna for a compact portable wireless device can have a relatively small size while exhibiting high efficiency. A planar ground structure for the antenna may be formed from a circuit board on which integrated circuits have been mounted. A curved inverted-F resonating element may be attached to the ground structure. A battery may be provided to power the compact portable wireless device. The battery may be used as a parasitic antenna element.
摘要:
Electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. An inverted-F antenna may have first and second short circuit legs and a feed leg. The first and second short circuit legs and the feed leg may be connected to a folded antenna resonating element arm. The antenna resonating element arm and the first short circuit leg may be formed from portions of a conductive electronic device bezel. The folded antenna resonating element arm may have a bend. The bezel may have a gap that is located at the bend. Part of the folded resonating element arm may be formed from a conductive trace on a dielectric member. A spring may be used in connecting the conductive trace to the electronic device bezel portion of the antenna resonating element arm.

摘要:
A multiband antenna operates in at least a first frequency band and a second frequency band, a higher frequency band. A dipole has a first conductive leg and a second conductive leg and may be directly fed between the first and second legs. At least a portion of the first leg of the dipole has a meander configuration. The first leg has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the first frequency band and the second leg has an electrical length of about one-quarter wavelength, or an odd multiple thereof, or more in the first frequency band. A non-driven parasitically-excited conductive element is closely spaced to the first dipole leg and is electrically connected to the second dipole leg. The parasitic element has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the second frequency band.
