Other embodiments are disclosed.

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.
