Abstract
The present invention relates to a display arrangement comprising a display means and receiving and/or transmitting means adapted to be arranged in association with said display means. An optically transparent and electrically conductive layer structure is adapted to be provided on the display means. Said optically transparent and electrically conductive layer structure is arranged or structured to form a plurality of receiving and/or transmitting elements constituting said receiving and/or transmitting means. Feeding and/or controlling means are provided to individually or groupwise feed and/or control said receiving and/or transmitting elements.
Claims19
A display arrangement, comprising
- a display means;
- an optically transparent and electrically conductive layer structure, adapted to be provided on a first side of said display means, and arranged to form a plurality of receiving and/or transmitting elements, wherein
- the receiving and/or transmitting elements further comprising an arrangement of antenna elements, and
- the antenna elements comprise antenna patches;
- a grounding conductive layer on a second side of said display means, which is opposite to said first side of said display means on which said receiving and/or transmitting elements are provided, said grounding conductive layer is adapted to act as a ground plane for the antenna patches;
- and
- feeding and/or controlling means coupled to the receiving and/or transmitting elements to individually or groupwise feed and/or control said receiving and/or transmitting elements, wherein the feeding means extend along the first side of the display means in a same plane as the antenna elements.
A method for receiving and handling multipath radio or millimeter wave or microwave signals in a display arrangement comprising a receiving/transmitting means arranged in association with the display means, the method comprising:
- receiving an individual spatially coupled signal in each of a number of receiving elements provided by means of an optically transparent and electrically conductive layer structure disposed on a first side of the display means, wherein
- the receiving elements comprise an arrangement of antenna elements,
- the antenna elements comprise antenna patches, and
- a grounding conductive layer is provided on a second side of said display means, which is opposite to said first side of said display means on which said receiving elements are provided, said grounding conductive layer is adapted to act as a ground plane for the antenna patches, and
- controlling receiving elements separately or groupwise, for feeding, combining and/or switching the signals received in the receiving elements using feeding means that extend alone the first side of the display means in a same plane as the antenna elements,
- using the display arrangement both for optical presentation and for reception of radio, millimeter waves or microwaves.
A method of handling and transmitting radio or millimeter wave signals or microwaves in an arrangement comprising a display means and a transmitting or receiving and transmitting means, the method comprising:
- switching and/or combining and/or multiplexing a number of radio, millimeter or microwave signals in a feeding, combining and/or switching distribution network associated with or in the display means,
- providing separate radio, millimeter or microwave signals to transmitting elements provided by means of an optically transparent, electrically conductive structure provided on a first side of the display means such that the display means can be used both for optical presentation and for radio, millimeter or microwave transmission, wherein
- the transmitting elements comprise an arrangement of antenna elements,
- the antenna elements comprise antenna patches,
- the feeding distribution network extends along the first side of the display means in a same plane as the antenna elements, and
- a grounding conductive layer is provided on a second side of said display means, which is opposite to said first side of said display means on which said transmitting elements are provided, said grounding conductive layer is adapted to act as a ground plane for the antenna patches.
