摘要:
A multi-frequency antenna includes a microwave substrate, a first antenna unit, a second antenna unit, a third antenna unit and a grounding unit. The first antenna unit, the second antenna unit, and the third antenna unit are disposed on the microwave substrate surface. The grounding unit is disposed at an edge on the surface of the microwave substrate. The grounding unit is in connection with the second antenna unit. The second antenna unit and the third antenna unit are bent to form perpendicular structures to the microwave substrate. The compact arrangement reduces the physical footprint of the antenna module to enable fitment in a wide range of products having tight special constraint.

A method for improving compatibility of a hearing aid with an antenna, in which at least a metal frame is provided near by a grounding surface of the antenna to change the direction of radiation of the antenna, thereby to enhance the directivity of the antenna on the side away from a hearing aid, and to reduce the quantity of radiation proceeding toward the hearing aid and to improve the near-field quantity (for about 3 dB) of an electric field of an HAC tested plane. This method can further increase the heights of the metal frames to reduce the near-field quantity of the electric field of HAC (hearing aid compatibility) tested plane.

The present invention provides a mobile phone antenna, which comprises an antenna ground plane, a radiating conducting plate, a feeding conducting strip, a shorting conducting strip, and a system ground plane. Using the antenna ground plane as a shielding metal wall, the present invention advantages itself of making the antenna and a shielding metal box easier to be integrated without a need for an isolation distance. The present invention thus makes the best use of the internal spacing of a mobile phone. This antenna is suitable for application as an embedded antenna for both folded-type and bar-type mobile phones. The operating bandwidth of this antenna can cover the required bandwidth for a Universal Mobile Telecommunication System operation.

An ultra-wideband (UWB) antenna is provided. It comprises a dielectric substrate, a ground plate, a metal plate, and a transmission line. The ground plate formed on the dielectric substrate has a first slot thereon. The metal plate formed on the dielectric substrate has a feed-point and a second slot thereon. The total length of the second slot is about a half-wavelength at the desired notched frequency for the UWB antenna. By embedding the second slot of a suitable length on the metal plate resided in the first slot, a band notched characteristic is achieved for the antenna in the 5 GHz band, thereby overcoming the problem of signal interference with the UWB operations. The disclosed antenna and the circuitry for the antenna system are easily integrated. With the simple structure, the fabrication cost for the antenna is also reduced.

An omnidirectional ultra-wideband monopole antenna, with the characteristics of simple structure, easy fabrication and low cost, mainly comprises a ground plane, a U-shaped radiating member above the ground plane and a feeding member for feeding signals to the radiating member. The radiating member further comprises a first sub-radiating member parallel to the ground plane, with a first side edge and a corresponding second side edge, a second sub-radiating member connected to the first side edge and perpendicular to the first sub-radiating member, forming a first angle therebetween, and a third sub-radiating member connected to the second side edge to form a second angle. The second sub-radiating member and the third sub-radiating member are extended in the same upright direction above the ground plane. The antenna can provide good omnidirectional radiation patterns for frequencies across a very wide operating bandwidth.
