- 2. ADVANCED DESIGN SYSTEM (ADS) Advanced Design System (ADS) is an electronic design automation software system produced by PathWave Design, a division of Keysight Technologies. It provides an integrated design environment to designers of RF electronic products such as mobile phones, pagers, wireless networks, satellite communications, RADAR systems, and high – speed data links.
- 3. MICROSTRIP Microstrip is a type of electrical transmission line which can be fabricated with any technology where a conductor is separated from a ground plane by a dielectric layer known as the substrate. Microstrip lines are used to convey microwave-frequency signals.
- 4. Coplanar Waveguide • Coplanar waveguide is a type of electrical planar transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. On a smaller scale, coplanar waveguide transmission lines are also built into monolithic microwave integrated circuits. • Conventional Coplanar Waveguide (CPW) consists of a single conducting track printed onto a dielectric substrate, together with a pair of return conductors, one to either side of the track.

- 7. Branch Line Coupler A Branch Line Coupler (Quadrature 90° Hybrid) is a four-port network device with a 90° phase difference between two coupled ports. The device can be used for a single antenna Transmitter/Receiver system or an I/Q signal splitter/combiner.

- 12. Wilkinson Power Divider • Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The Wilkinson design can also be used as a power combiner because it is made up of passive components and hence reciprocal. First published by Ernest J. Wilkinson in 1960, this circuit finds wide use in RF Communication Systems utilizing multiple channels since the high degree of isolation between the output ports prevents crosstalk between the individual channels. • It uses quarter wave transformer, which can be easily fabricated as quarter wave lines on printer circuit board. It is also possible to use other forms of transmission line (e.g. coaxial cable) or lumped circuit elements (inductors and capacitors).
