Abstract: An integrated multi-band antenna comprises a first conductor, a second conductor, at least one inductor member, an extension conductor, and a grounding plane. The first conductor and a first branch of the second conductor form a first coupling region. The inductor member is arranged near the first branch. The extension conductor is arranged near a second branch of the second conductor and extends therefrom to form a terminal. The terminal and first conductor form a second coupling region. The first and second coupling regions are arranged on opposite sides of the first conductor. The second branch connects to the grounding plane. The present invention adopts a design incorporating the capacitive coupling of the conductors and the choke of the inductor member, integrates the standard frequency bands of the low-frequency and high-frequency systems of the digital TV to achieve a miniaturized digital TV antenna spanning a wide range of frequency bands.

Abstract: A digital television antenna comprises a baseplate having a first surface and a second surface; a radiation conductor arranged on the first surface and having a main portion and extension portions; a coupling conductor arranged on the second surface and corresponding to the radiation conductor, wherein a first conductor and a second conductor extend from one end of the coupling conductor and wriggle on the second surface; a short-circuit member, wherein one end of the short-circuit member is connected to another end of the coupling conductor; and a grounding plane connected to another end of the short-circuit member. The coupling of the radiation conductor, the coupling conductor, the first conductor and the second conductor provides the standard frequency bands of the digital TV, whereby the antenna volume is greatly reduced, wherefore the digital TV antenna of the present invention features both a wide bandwidth and a miniaturized size.

Abstract: A broadband antenna with a connection device comprises a connection unit, a signal member and a radiation conductor. The connection unit has a first side and a second side. A fixing member is arranged on the first side. The signal member is arranged inside the connection unit and has a central cable. The central cable enters the first side and emerges from the second side to form a terminal. The radiation conductor is joined to the terminal of the central cable. The connection unit is engaged with a connection interface of an electronic device. A metallic material is used to fabricate the connection unit to increase the volume of the radiation conductor, whereby the transmission bandwidth of the antenna is greatly increased. The signal member is arranged inside and integrated with the connection unit, whereby the broadband antenna is easier to assemble, and the signal is less likely to attenuate.

Abstract: A broadband antenna has a substrate, a coupling conductor, a conductor string, a ground conductor and a ground plane. The coupling conductor has a first coupling member and a second coupling member being separated from each other. The conductor string and the ground conductor are connected to the second coupling member. The conductor string extends along a direction opposite to the second coupling member. The ground conductor is connected to the ground plane. The broadband antenna uses the coupling conductor and the ground conductor to adjust input impedance for impedance match. The conductor string functions as a multi level resonance circuit to increase impedance bandwidth.
