摘要： The present invention provides an integrated antenna and visual display apparatus, or one of an antenna apparatus and visual display apparatus which is integratable with the other. Apertures are formed in a visual display, such as an OLED display. The apertures when formed in a conductive layer operate as radiating bodies of an antenna array. A subset of sub-pixels of the visual display can be removed in line with the apertures. An optically transparent substrate is located over the visual display, and an array of further conductive elements, which may be optically transparent, is disposed on an exterior of this substrate. The further conductive elements operate to direct the antenna signals through the substrate, by coupling in an impedance-matched manner with the radiating apertures.

摘要： A high-gain, low-sidelobe, beam-steerable antenna includes a liquid-crystal loaded composite right- and left-handed (CRLH) metamaterial array. The metamaterial array includes a pair of first and second rows of unit cells, to propagate a radiation pattern along a first axis. One row can operate in left-hand mode, and the other row can operate in right-hand mode. Each unit cell in the metamaterial array includes a volume of liquid crystal and at least one isolated ground patch. The isolated ground patch being is as a virtual ground connection capable of generating a potential difference for tuning the dielectric value of the liquid crystal. The first and second rows are oriented end-to-end along the first axis and separated from each other by a first distance. The antenna includes a phase variable liquid-crystal loaded lens that is controllable to be phase variable along a second axis orthogonal to the first axis.

摘要： A transmitarray, or radio frequency lens, can provide a large variation of time-delay. The transmitarray comprises a number of time-delay unit (TDU) cells that each have a capacitive patch and a rectangular wire loop separated by dielectric material. The rectangular wire loop allows current continuity to be maintained between adjacent TDU cells, even when different sized TDUs are included in the transmitarray.

摘要： An antenna architecture containing a broadband resonant cap positioned over a radiating patch is disclosed. The resonant cap consists of a rectangular resonant patch at the center with parasitic patches in close proximity of the four edges of the resonant patch. The parasitic patches may be coplanar with the resonant patch or may be mounted at an angle with respect to the vertical axis of the resonant patch. The resonant cap reduces the HPBW of the emitted radiation and improves emission directivity.

摘要： A low loss beam forming method and antenna structure are disclosed. The method and structure may preferably be used in forming two narrow beams within a cellular sector. This method allows an increase in the overall network capacity by using a three-column non-planar array and a compact, low-cost, low-loss 3-to-2 Beam-Forming Network (BFN). This structure produces two symmetrical beams with respect to the azimuth boresight. Radiation patterns of the two beams are designed to cover the entire azimuth coverage angle of a cellular sector with minimum beam-split loss and cross-over losses.

摘要： An electronically beam-steerable full-duplex phased array antenna is described. The phased array antenna includes an array of a plurality of radiating elements. The array includes at least one column having a plurality of radiating elements, and the array is configured to generate a radiation field. The phased array antenna includes a metasurface over the array of radiating elements. The metasurface introduces a phase shift to the radiation field of the array, to cause a beam of the phased array antenna to be angularly offset from the radiation field of the array.
