摘要： Embodiments are provided for an antenna element design with high aperture efficiency and stable gain across a frequency range. In an embodiment, the antenna element is obtained by placing a conductive layer on a dielectric substrate, forming a slot in the conductive layer, and forming two feed lines inside the dielectric substrate. A dielectric layer is placed on the dielectric substrate and over the conductive layer and the slot. A circular or elliptical conductive wall is formed inside the dielectric layer. A conductive element is also formed on the dielectric layer and over the slot. One or more second dielectric layers are placed on the dielectric layer and over the conductive element. A second circular or elliptical conductive wall is formed inside each second dielectric layer. A second conductive element is also formed on each second dielectric layer, over the conductive element.

摘要： An antenna, especially for use with a handheld RFID reader for scanning RFID tags oriented in different orientations, includes a feeding port located on an axis for supplying an RF signal to a primary antenna member for transmitting and receiving electromagnetic waves. A secondary antenna member is juxtaposed with the primary antenna member for re-radiating the electromagnetic waves propagated by the primary antenna member. Each antenna member includes one antenna element extending in a radial direction away from the axis and continuing along at least one turn in a turning direction at least partly about the axis, and another antenna element extending in an opposite radial direction away from the axis and continuing along at least one turn in the turning direction at least partly about the axis. The electromagnetic waves have congruent slant polarizations each having components in both of two mutually orthogonal planes to read the tags.

摘要： In order to have an antenna apparatus small in size and capable of switching its directivity pattern to be adaptive to multiple frequencies, the present invention provides an antenna apparatus having a first antenna element formed at an approximately center position of a planar printed circuit board and second antenna elements formed before and behind the first antenna element. It is possible to construct an antenna in which the first antenna element functions as a radiator and the second antenna elements function as a director or a reflector, respectively, by changing electrical length of the second antenna elements. The antenna becomes adaptive to multiple frequencies by feeding the second antenna elements at different phases to have the second antenna elements functioning as radiators.
