A measuring head for a microwave band formed by two horizontal metal plates mounted one over the other, which on the lower plate has a an asymmetrical strip-line board positioned on it while next to the microstrip line there is placed a test sample, and to both ends of the microstrip line there are directly attached standard microwave sockets which constitute the head input and output, pursuant to the patent no 145 580, characterised in that the head is provided with a sample stage (5) made of material of a dielectric constant <=10, on which there is placed a test sample (1), while the distance L1 between the upper metal plate (4) and the top surface of the test sample (1) is so adjusted that it is not less than the sample stage height (Lt) and less than the test sample height (L), that is Lt<=L1<=L.<IMAGE>
