The invention relates in part to a folded dipole having a dipole axis and a pair of arms which together have a profile which is concave on one side and convex on the other when viewed along the dipole axis. The dipoles may be arranged as a dipole box around a central region, typically in a generally circular or square configuration. Further elements may be placed in the dipole box or in the gaps between dipole boxes. The antenna may be a single-band antenna, or a multi-band antenna with the further elements operating in a different frequency band to the dipole boxes. The further elements may be concentric dipole boxes. The invention is particularly suited for use in a cellular base station panel antenna. A novel coaxial to microstrip transition is also described.

Dipole antennas and coaxial to microstrip transitions

A method and apparatus are provided for constructing a multi-band antenna (). The method includes the steps of providing a plurality of combination-type dipole assemblies (, FIG.) each defined by a box-type dipole array () disposed coaxially within a circular-type dipole array (), disposing the plurality of combination-type dipole assemblies along a substantially straight line () over a ground plane () and disposing a plurality of crossed-type dipole antenna arrays along the substantially straight line in alternating order with the plurality of combination-type dipole assemblies.

A fully integrated portable personal computing device includes a lid body member and a main body member. An input system inputs data and commands and a microprocessor processes the data in accordance with the commands. A display system displays information. The display system is located in the lid body member. A projection system is integrally included in the portable personal computing device for projecting the information displayed on the display system to an area remote of the portable personal computing device. The projection system can also be a peripheral plug-in device for replacing a floppy disk drive peripheral for the portable personal computing device.
