Abstract: A monofrequency antenna integrated with a coaxial feed cable comprises a first conductor, a second conductor and a feed cable. The feed cable includes a coating layer, an outer conductor, an insulating layer and a central conductor. The coating layer is formed on the outmost surface of the feed cable. The outer conductor is formed on the inner surface of the coating layer, extends in two opposite directions, and connects with the second conductor. The insulating layer is formed on the inner surface of the outer conductor and extends in two opposite directions. The first conductor is formed on the inner surface of the insulating layer and extends along one direction. The central conductor is formed on the inner surface of the insulating layer and extends along a direction opposite to the direction along which the first conductor extends. The present invention simplifies antenna structure and promotes transmission efficiency.

Abstract: An antenna with an improved holed system ground plane comprises a substrate, a radiation conductor member, a grounding member and a system ground plane. The radiation conductor member is arranged on the surface of the substrate. The grounding member is arranged on one edge of the substrate. The radiation conductor member is connected with the grounding member. The system ground plane is connected with one side of the grounding member. The system ground plane has at least one arbitrary-shaped hole. A radiation-enhancing filler is disposed in the arbitrary-shaped hole. The present invention solves the conventional problems that the system ground plane is drilled or cut to accommodate components and IC chips, keep away from wiring routes and avoid protrusions on the appearance, via disposing radiation-enhancing fillers in the arbitrary-shaped holes. Thereby is kept integrality of the system ground plane and promoted omnidirectionality of signal transmission.

Abstract: A multi-frequency antenna comprises a first conductor, a second conductor, a grounding member, and a third conductor. The first and second conductors are respectively arranged on a first plane and a second plane. The grounding member is arranged on a third plane existing between the first and second planes. The third conductor is connected with the first conductor and arranged on the first plane also. The first and third conductors are respectively coupled to the radiation signals of the second conductor to form a first path and a second path. The first path and the second path have a phase difference of 180 degrees. The present invention features the additional third conductor. The third conductor and the first conductor are coupled to the radiation signals of the second conductor to generate opposite-phase signals. Thus are counterbalanced the interferences among the antenna systems of an identical frequency band.

Abstract: A thin-film antenna comprises a plastic member, a flexible radiation conductor and a conduction member. The plastic member has an accommodation space. The flexible radiation conductor is disposed on one surface of the accommodation space. The conduction member has a contact terminal physically contacting the flexible radiation conductor. The flexible radiation conductor is embedded on one surface of the accommodation space of the plastic housing of a wireless communication device via a hot pressing process. The flexible radiation conductor can replace the conventional complicated rigid metallic radiation conductor to reduce thickness of products. The conduction member has a conductive metallic thimble for conducting electric signals, which can prevent the thin-film radiation conductor from protruding or breaking.

Abstract: A flexible antenna comprises a filmed layer, a flexible radiation conductor and a support member. The flexible radiation conductor has a crooked form and a feeder terminal. The filmed layer covers the upper surface of the flexible radiation conductor. The support member has a through-hole. The lower surface of the flexible radiation conductor is stuck to the upper surface of the support member. The feeder terminal is inserted through the through-hole to protrude from the lower surface of the support member. The flexible radiation conductor and the crooked feeder terminal thereof replace the conventional radiation conductor circuit layer and metallic contact terminal to overcome the problem that the conventional contact terminal damages the radiation conductor layer and protrudes the filmed layer. Further, the present invention integrates FPC and LDS technologies to enable the flexible radiation conductor to be arbitrarily stuck to complicated planes or complicated curved surfaces.
