摘要： The present invention relates to a self-grounded antenna arrangement (10) comprising a base or central portion (5) arranged in a first plane and a number of arm sections (1,2,3,4) associated with said central portion (5), which taper towards a respective end tip. It comprises an electric conducting material, each arm section being adapted to form a transition from the central portion and being bent backwards towards the central portion by more than 180° so that its end tip approaches a first side of the central portion, at an opening therein. The end tip is connected to feeding means for feeding via an arm section specific port, one specific port ( 11 1 , 11 2 ,11 3 ; 11 4 ;) for each arm section. Each arm section (1,2,3,4) comprises a mixed functionality of a curved monopole antenna and a loop antenna, and the antenna arrangement provides substantially uncoupled ports with far field functions that are almost orthogonal in polarization, direction or shape. The invention is in particular intended for use in MIMO antenna systems for statistical multipath environments.

摘要： Improvements in relation to an apparatus for measuring the performance of a device under test, such as an antenna, a mobile phone and other wireless terminals, are disclosed. The chamber defines an internal cavity therein, adapted to enclose the device under test, and including walls of an inwardly reflective material, rendering the walls reflective to electromagnetic waves, thereby simulating a multi-path environment. Thus, the chamber is a reverberation chamber. At least one moveable object and chamber antenna are arranged in the cavity. A measuring instrument is connected to the device under test and the chamber antenna, for measuring the transmission between them. Further, an improved antenna holder is disclosed, comprising three surfaces of a reflective material, said surfaces extending in planes which are orthogonal in relation to each other and each surface facing away from the other surfaces, and wherein a chamber antenna is arranged on each of said at least three surfaces. Other improvements relate to video surveillance, channel emulation and shielding.
