An antenna device includes a differential antenna and a first balun. The differential antenna includes a first radiator, a first antenna port and a second antenna port connected to a first surface of the first radiator. Orthographic projections of the first antenna port and the second antenna port projected to the first radiator are symmetrical to a midpoint of the first radiator. The first balun is located on one side of the first surface of the first radiator, and its orthographic projection on the first plane where the first surface is located overlaps the first surface. The first balun includes a first port, a first wiring, a first coupling structure electrically connected to the first antenna port, and a second coupling structure electrically connected to the second antenna port. Neither the first coupling structure nor the second coupling structure directly contacts the first wiring.

Antenna device

A broadband linear polarization antenna structure, including a reference conductive layer, a first patch antenna, a second patch antenna, and a feeding portion, is provided. The reference conductive layer includes through holes. A first short pin is connected between the reference conductive layer and the first patch antenna, and a second short pin is connected between the first patch antenna and the second patch antenna. Each feeding portion penetrates the reference conductive layer through the through hole and is coupled to the first patch antenna.

Broadband linear polarization antenna structure

An antenna device, including a case assembly, a first waveguide assembly, and a second waveguide assembly, is provided. A cavity is defined by an interior of the case assembly, and a first side of the case assembly has a slot penetrating the case assembly. At least part of the first waveguide assembly is located within the cavity and is connected to the first side. A projection of the first waveguide assembly to the first side is symmetrically located on two sides of the slot. The second waveguide assembly is located outside the case assembly, is close to the first side, and is connected to the slot. The second waveguide assembly is suitable for transmitting an antenna signal to the cavity through the slot and the first waveguide assembly. The antenna signal resonates in the cavity and radiates outward from a second side of the cavity opposite to the first side.

Provided is a rapid over-the-air (OTA) production line test platform, including a device under test (DUT), an antenna array and two reflecting plates. The DUT has a beamforming function. The antenna array is arranged opposite to the DUT, and emits beams with beamforming. Two reflecting plates are disposed opposite to each other, and are arranged between the DUT and the antenna array. The beam OTA test of the DUT is carried out by propagation of the beams between the antenna array, the DUT and the two reflecting plates. Accordingly, the test time can be greatly shortened and the cost of test can be effectively reduced. In addition to the above-mentioned rapid OTA production line test platform, platforms for performing the OTA production line test by using horn antenna arrays together with bending waveguides and using a 3D elliptic curve are also provided.

Rapid over-the-air production line test platform

The disclosure provides an ultra-wideband non-metal horn antenna, which includes three combinable non-metal elements such as an impedance matching member, a field adjustment member and an outer cover member. The impedance matching member and the field adjustment member are respectively disposed with a first and second groove structures. The field adjustment member is connected between the impedance matching member and the outer cover member. Therefore, the horn antenna of the disclosure can have a more symmetrical radiation pattern, a smaller antenna size, and ultra-wideband performance.

Ultra-wideband non-metal horn antenna

An antenna structure and an electronic device are provided. The antenna structure includes a connecting part, a grounding part, a first extending part and a second extending part. An angle is larger than zero between a first vector from the connecting point to the first open terminal and a second vector from the connecting point to the second open terminal. Also, a difference between the path length of a first path length and the path length of a second path length would be a quarter of the wave length of the radio frequency signal or a positive integer times thereof, so that the antenna is capable of receiving the radio frequency signal with circular polarizing.
