A portable electronic device with function of receiving and radiating radio frequency (RF) signal and a multi-frequency antenna thereof are disclosed. The portable electronic device comprises a RF module and a multi-frequency antenna connecting to the RF module. The multi-frequency antenna comprises a helix element and a coaxial cable disposed within the helix element. The helix element comprises a first helix portion and a second helix portion adjacent to each other, and the coaxial cable comprises a grounding portion and a radiating portion. The first helix portion covers the grounding portion, and the radiating portion is disposed within the second helix portion separated with each other.

Multi-frequency antenna

An antenna comprises a first transmission element, a second transmission element, a conductive element, a ground element, a ground line and a signal line. The conductive element is connected to the ground element. The first transmission element is connected to the conductive element. The first transmission element comprises a first spiral structure and a first axis. The second transmission element is connected to the conductive element. The ground line is electrically connected to the ground element. The signal line is electrically connected to the conductive element at a feed point.

Antenna

A multi-frequency antenna for receiving a first frequency and second frequency signals comprises a grounding element, a first conductive member, a first radiation member, and a second radiation member. The first conductive member connects to the grounding element. The first radiation member and the second radiation member connect to the first conductive member separately. The multi-frequency antenna further comprises a parasitic structure. The parasitic structure structurally encircles the second radiation member and the encirclement is a partial encirclement. Moreover, the parasitic structure connects to the grounding element.

A metal complementary element of a grounded self-complementary antenna for an electronic device and a metal grounding element of the electronic device contact with each other, are electrically connected to each other or are a same article so as to substantially enlarge an area of a grounding end of the self-complementary antenna to enable the self-complementary antenna to have the good radiation efficiency and the broader bandwidth such that the radio signal transmission effect of the electronic device can be elevated.

Grounded self-complementary antenna for electronic device

An antenna comprising a ground element, a first conductive element, a first transmission element, a second transmission element and a third transmission element. The first conductive element is connected to the ground element. The first transmission element is connected to the first conductive element extending in a first direction. The second transmission element is connected to the first conductive element. The third transmission element is connected to the first conductive element extending in a second direction opposite to the first direction, wherein the third transmission element nears the second transmission element, and maintains a distance from the second transmission element.

Electronic device and antenna thereof

A miniaturized planar antenna of digital television comprises an insulation plate a metal radiator combined with a first surface thereof, a metal grounding element connected to a second surface thereof and a metal parasitic element. The metal radiator has a meander line portion and the metal parasitic element also has a meander line portion and is corresponding to a position of the metal radiator; the transmission efficiency of digital television signals can be elevated by broadening an electromagnetic signal receiving bandwidth of the antenna by means of the metal parasitic element.

Miniaturized planar antenna of digital television

A wideband antenna includes a substrate, a radiator, a signal feeding element, and a grounding element. The radiator includes a first child radiator and a second child radiator.
