摘要： Present teachings relate to an antenna arrangement comprising, a first substrate comprising a first surface and a second surface, the first surface and the second surface being opposite sides of the first substrate, a second substrate comprising a third surface and a fourth surface, the third surface and the fourth surface being opposite sides of the second substrate, a patch antenna being realized in a first electrically conductive material attached to the first surface, a ground plane being realized in a second electrically conductive material attached to the second surface, and at least two feeds realized in a third electrically conductive material attached at least partially to the fourth surface. The patch antenna is arranged with respect to the ground plane so as to form a resonant antenna. The first substrate and the second substrate are adapted to be held in close proximity or in contact such that the third surface is facing the second surface, and each of said at least two feeds are having an individual corresponding opening in the ground plane for capacitively coupling each of said at least two feeds to the patch antenna, wherein footprint of each of said at least two feeds is smaller than footprint of its corresponding opening in the ground plane. Present teachings also relate to an antenna arrangement where the second substrate is replaced by a dielectric layer, and to a wireless device comprising the antenna arrangement.

摘要： Present invention is a wireless device comprising a Van Atta array, said Van Atta array comprising a plurality of antenna pairs, each of said antenna pairs comprising two antenna elements electrically coupled by a signal path of pre-determined length. The wireless device further comprises a measurement unit, said measurement unit is adapted to perform electrical measurements between two measurement points. One of said two measurement points is located at a first pre-determined location on the signal path of one of the antenna pairs, and the other of said two measurement points is located on a second pre-determined location on the signal path of one of the other antenna pairs. The present invention is also a method for retro-reflection of an incident wave using a plurality of antenna pairs.

摘要： A radio system is provided which comprises a radio receiver and a processing system, wherein the radio receiver is configured to detect radio signals transmitted from a radio transmitter on a plurality of frequency channels, and to measure respective signal strengths of the radio signals for each of the plurality of frequency channels. The processing system is configured to evaluate a measure of statistical dispersion of the respective signal strengths over the plurality of frequency channels, and to use the measure of statistical dispersion to determine information relating to a proximity of the radio transmitter to the radio receiver.
