“…The reported power dividers [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ] can be classified into active and passive types. Active power dividers usually use two common-drain FETs [ 13 ] or Darlington cell [ 14 ] topologies to achieve single-to-differential outputs by adopting advanced processes.…”

“…Despite the advantage of compact size, active dividers are unsuitable for portable systems due to extra power dissipation. Passive dividers, on the other hand, are mostly realized in monolithic microwave integrated circuit (MMIC) technology [ 15 , 16 , 17 , 18 ] and are seldom performed in MEMS process [ 19 ] to split unequal power signal into differential. However, it is still a challenge to implement a power divider with miniaturized size by cause of the limitation of wavelength.…”

This paper presents a transformer-based power divider with six-port suspending structure for 2.4 GHz wireless applications. The proposed power divider, which is featured with chip size (2.9 mm × 2.8 mm × 21 μm), was constructed by an 8-μm-thick Cu bottom electrode, a 5 μm-height supporting copper post, and an 8-μm-thick suspended spiral copper conducting layer with a 13 μm air gap. The main structure included two transformers and six input/output matching capacitors for simultaneously achieving two single-to-differential paths so that the chip size of the complex multiple-ports transceiver could be reduced. According to the results, the proposed divider has characteristics of the radio frequency (RF), and its input return losses are around −10 dB, output return losses are beneath −10 dB, and minimum amplitude imbalance is below 1.5 dB and less than 1° phase imbalance at 2.4 GHz operating frequency.

The study of metamaterials has experienced rapid growth, particularly with the discovery of left-handed metamaterials. One promising technology for controlling electromagnetic waves in small structures is transmission-line metamaterial (TL-MTM), which can accurately determine various parameters, such as working frequency, bandwidth, and phase offsets. Antennas are essential components for receiving and transmitting signals in RF systems. Although the microstrip antenna is a popular choice due to its low cost and ease of manufacturing, it is limited in terms of size and frequency range. In this chapter, more than 100 papers are reviewed based on their methodology and performance to discuss various techniques for improving antenna performance, such as the use of artificial neural networks (ANN) and metamaterials. The insights presented in this chapter will aid in identifying, analyzing, and synthesizing the latest developments in the field of metamaterials.
