ELECTRONIC PACKAGE

An electronic package includes a circuit structure having a first metal layer, a packaging layer formed on the circuit structure, and a second metal layer formed on the packaging layer and separated from the first metal layer at a distance. The first metal layer and the second metal layer constitute an antenna structure. Since the second metal layer is formed on a portion of a surface of the packaging layer, a propagating wave emitted by the first metal layer cannot pass through the second metal layer, but a surface of the packaging layer not covered by the second metal layer. Therefore, the propagating wave can be transmitted to a predetermined target, and the electronic package performs the function of an antenna.

WIDEBAND REFLECTARRAY ANTENNA FOR DUAL POLARIZATION APPLICATIONS

A wideband reflectarray antenna for dual polarizations application is formed by an array of phasing cells, where each cell contains two orthogonal or quasi-orthogonal sets of parallel conductive dipoles printed on two levels of a multilayered grounded substrate. The dipoles for each polarization are coupled in both horizontal and vertical directions, providing a large broadband operation and low cross-polarization with only two levels of metallizations. The antenna is designed by adjusting the lengths of the dipoles to produce the phase-shift required to collimate or shape the radiated beam in dual-polarization when illuminated by a feed, either in broadband or dual-frequency operation. The invention also relates to a design and manufacturing method for producing the reflectarray antenna, based on the optimization of the dipole lengths for each phasing cell.

CONFORMAL WAVEFRONT TRANSFORMER AND METHOD OF MAKING

A wavefront transformer for reflecting and transforming an incident electromagnetic wavefront includes an electrically-conductive substrate with spaced perforations (cavities), which may have uniform spacing and varying depth. The perforations may have a radius that is close to and greater than a cutoff radius for one or more intended incident frequencies of the incident wavefront. The spaced perforations may be filled with air or may be filled with a dielectric solid material. The substrate may be covered with a cover made of a dielectric solid material. The transformer may be made by drilling holes in the substrate. Alternatively a plate having protrusions on it corresponding to the desired perforations may be used to form the perforations on the substrate. The plate may be removed or left in place after the formation of the perforations.
