An antenna structure includes a metal frame, at least one feed source, and a feed portion. The metal frame includes at least one radiating portion and at least one slot. The at least one slot is disposed in the at least one radiating portion or adjacent to the at least one radiating portion. The at least one feed source and the at least one radiating portion form a first antenna. The feed portion and the at least one slot form a second antenna. The at least one feed source supplies an electric current for the first antenna, thereby exciting a first working mode and generating a radiation signal in a first frequency band. The feed portion spans the at least one slot to supply the electric current for the second antenna, thereby exciting a second working mode and generating a radiation signal in a second frequency band.

Antenna structure

An antenna structure applied in a wireless communication device includes a metal frame. The wireless communication device includes at least one electronic component. The metal frame includes a substrate. The substrate includes an antenna. The antenna includes a feed portion and a gap. The feed portion spans the gap. The metal frame is spaced from the electronic component. A clearance is formed between the metal frame and the electronic component.

An antenna and antenna module with a structure increasing radio wave coverage but reducing cross interference between modules includes a circuit board in the shape of an octagon and four antenna modules. The circuit board thus includes eight side surfaces, and the four antenna modules are respectively disposed on four non-adjacent side surfaces of the octagon. Each antenna module is electrically connected to the side surface by a feed portion. A wireless communication device using the antenna structure is also disclosed.

Antenna structure and wireless communication device using the same

An antenna structure includes a metal frame. The metal frame includes a first surface, a second surface, and a third surface. The third surface is located between the first surface and the second surface. The metal frame includes at least one antenna. The at least one antenna includes a first gap, a second gap, and a feed portion. The first gap is disposed between the first surface and the second surface. The second gap is disposed in the third surface. The feed portion is mounted on the first surface and spans the first gap. When the feed portion supplies an electric current, the electric current is coupled to the first gap and the second gap.

An antenna structure serving as an emitter in a radar device with optimized isolation of signal comprises antenna array as the radiating element. The antenna array includes array units. Each array unit includes radiating units connected by a feeder. Radiation area of each radiating unit gradually decreases from a center of array unit to ends of array unit. A specified distance is defined between centers of adjacent radiating units along an extending direction of the feeder. The feeder transmits a current signal to the array units, the radiating unit emits a radar scanning beam based on the current signal.

Antenna structure for optimizing isolation of signal and electronic device using same

An antenna structure suitable for 5G use includes first and second antenna units. Each second antenna unit is positioned between adjacent first antenna units. Each first antenna unit is positioned between adjacent second antenna units. Each first antenna unit and each second antenna unit are restricted to emit a radio beam in a single polarization. The first antenna unit emits radio waves in a first polarization, the second antenna unit emits waves in a second polarization. The first polarization direction and the second polarization direction are perpendicular to each other.
