An antenna arrangement including: a coupling element,a conductive element; an extension element for electrically extending the conductive element and a reactive element. The pinned layer has a planar shape which is long in the fixed magnetization direction and which is short in a direction orthogonal to the fixed magnetization direction. Air vents are provided in the form of either elastic material or slits, and one or more of the vents can be provided with an adjustable fastener which allows the clothing to expand to fit. It also has the advantage of enabling a culture system which can reflect effects of systemic environments on T cell responses to specific stimuli including antigen, by either culturing in the presence of such drug or analyzing the blood of a human or animal receiving such drug. Consequently, enhanced area efficiency may be achieved compared to conventional strategies, in which the resistive structures may have to be provided on the basis of a gate electrode metal, while, nevertheless, a low parasitic capacitance may be accomplished due to providing the resistive structures above the isolation structure.
