An antenna includes a radiator and a balun structure. The radiator includes a first branch for a first current to flow through and a second branch for a second current to flow through. The first branch and the second branch are arranged on two opposite sides of the balun structure. A direction of the first current is at least partially opposite to that of the second current. The first branch is spaced from the balun structure by a first slot. The second branch is spaced from the balun structure by a second slot. The first slot is configured to form a first horizontally-radiated electric field by the first current and a current on the balun structure. The second slot is configured to form a second horizontally-radiated electric field by the second current and the current on the balun structure.

An antenna device includes a first antenna and a second antenna. The first antenna receives or transmits first radio frequency signals to a first direction.

An antenna device comprising a base plate, a first radiator, a first balun and a second radiator. The base plate having a substantially planar shape. The first radiator is configured to radiate a first electromagnetic signal in a first frequency band. The first balun extends along a first axis between the base plate and the first radiator. The first axis is oriented perpendicular to the base plate and the first radiator. The first balun is arranged in order to support the first radiator. The second radiator is configured to radiate a second electromagnetic signal in a second frequency band. The second radiator includes one or more planar structures extending along the first axis and arranged between the base plate and the first radiator. The first and the second radiator operate in different frequency bands without any interference to form a compact multiband antenna device.

A wideband dual-polarized hourglass-shaped with wedge antenna for a 3G/4G/5G base station is designed using characteristic mode analysis to adjust resonant frequencies. The proposed antenna has a wide bandwidth when adding two pairs of wedges on the radiator, yielding two linear polarizations ±45°, and fulfilling all the requirements of 3G/4G and 5G antenna elements. The antenna is mechanically designed and easy to fabricate with die-casting, thus saving cost since only a single die is required for mass fabrication with low errors and large quantities.

A portable information handling system or docking station glass ceramic housing integrates antenna conductive wires in a first glass ceramic piece and a director conductive wire in a second glass ceramic piece coupled to the first ceramic glass piece, such as with optically-clear adhesive. A conductive contact interfaces the antenna conductive wire by exposure at the glass ceramic housing interior where pogo pins of a printed circuit board assembly bias against the conductive contacts to communicate the radio signals. The director conductive wire provides a parasitic element for directional control of the wireless signal. Ground conductive wires may integrate in the exterior side of the second glass ceramic piece and interface with the radio to provide a dipole antenna.

A portable information handling system glass ceramic housing integrates plural wires on opposing sides that interface with a radio to provide a dipole antenna, such as with a radio conductor output interfaced at a wire of the interior side and a radio ground output interfaced at a wire of the exterior side. Conductive contacts interface with the wires by exposure at the glass ceramic housing interior where pogo pins of a printed circuit board assembly bias against the conductive contacts to communicate the radio signals.
