Multilayer meander structures for wireless communications are presented in this paper. The miniaturization of meander structures is solved by positioning the meander conductor in multiple layers. The influence of the increasing number of layers and connecting vias on the operational parameters of the meander structures is investigated. Three-dimensional models of the meander structures are designed and analyzed in the CST Microwave Studio© software package. The general mathematical model of the meander structure is presented. The computer-based simulation is verified by a physical experiment and analytical calculations. The investigation shows that it is possible to miniaturize the meander structure by placing it into different layers and connecting the meander conductors with vias. The overall length of the meander structure is decreased by 48% from 16.24 mm to 8.4 mm, while the delay time td is changed only by less than 3.2% and increased till 1.145 ns, which is 35 ps. The overall dimensions of the miniaturized meander structure are 8.4 × 17.35 × 0.76 mm. The designed structure is suitable for operation at a 2.4–2.5 GHz ISM frequency band.

A CMOS broadband 1:4 active power divider is proposed in this paper. The power splitter can be used in Phased Array Transceivers at the Transmitter side. It is based on a cascode 1:4 current splitter and transmission lines. Compared to other passive power dividers and active power dividers, the proposed design exhibits 1-2 dB power gain and smaller area. The measured input 1dB compression point is 6 dB whereas the IIP3 is 7.2 dBm. The Noise Figure of the Power Divider is 10 dB at lower frequencies and 15 dB at 28 GHz. The measured results are performed across several chips. Realized in 22nm CMOS FDSOI from GF, the total power consumption is 29 mW from a 1 V power supply and the area occupied by the divider is 700µm x 600µm. A thorough analysis of the gain and noise of the divider is presented as well.
