摘要： A dual band end fed dipole provides at least two distinct operating frequencies, e.g. 2.45 GHz and 5.5 GHz. Properties of the antenna include low cost to manufacture, e.g. ease of automation; minimal manual labor to manufacture, e.g. reliability; dual band operation; broad bandwidth; good feed line isolation; omnidirectional beam pattern; minimal vertical beam squint; small diameter; and high efficiency. Embodiments of the invention provide a dual band end fed dipole with a low band trap on the feed side that requires minimal manual labor to manufacture because the antenna is formed from a single flat sheet of metal and soldering is replaced with crimping. Minimal dielectric loading is also achieved.

摘要： An antenna system is provided in a portable electronics device having a printed circuit board assembly. The antenna system includes a first antenna and a second balanced antenna provided on the printed circuit board assembly. The first antenna is fed from a portion of the printed circuit board assembly such that a ground plane of the printed circuit board assembly serves as a counterpoise for the first antenna. The second balanced antenna has dipole ends configured and oriented to generally minimize coupling to the ground plane of the printed circuit board assembly to increase isolation between the first antenna and the second balanced antenna.
