„5G Key Technologies:
What They Have to Do With Antennas?”
What is the 5th generation (5G) wireless communication? Nobody could tell us an exact definition at present. However, some emerging and potential technologies have attracted more and more attention. Of which, massive MIMO, millimetre wave, Beamforming, Full Duplex technologies are considered to be the key technologies for 5G wireless communications. Traditionally, the antenna in mobile communication systems is a passive element and generally is separated from the RF transceivers. To design the future antennas for mobile terminals, not only the bandwidth and antenna efficiency need to be acceptable, but also beam pointing and beam coverage is essential knowledge of the mobile channel. It is expected that the antennas or the antenna system will be adaptive. Moreover, the antennas or the system should not only cover the new frequency bands but also can be tightly integrated with the existing systems (4G) and evolutions of the 4G system primarily at the conventional sub-6 GHz bands. Several structures are available for designing multiband antenna such as planar inverted-F antenna (PIFA), monopole antenna and slot antenna etc. For example, by using monopole element, multiple resonances can be excited to cover large bands with reasonable system size. Moreover, at either lower microwave band or millimetre wave band, the antenna will be seamlessly integrated with RF transceivers and even with RoF or ADC (DAC) and E/O (O/E). Nowadays, for instance, mobile phones are required to be thin, elegant and have metal body along with other electrical requirements such as supporting multiple radios, large battery, high resolution display and camera etc. Several multiband antennas are required with sufficient isolation between them to support multiple radios and are essential for multifunctional devices. Therefore, the antenna for 5G communication systems will have distinct characteristics compared to traditional antennas. The tutorial will focus on the recent research advances in 5G antennas in interaction with the 5G Key technologies ingredients. It will be a good opportunity for students, professors and researchers in the field to brainstorm on and to identify the antenna’s requirements to satisfy the 5G key emerging technologies.

„Noise in Linear Circuits”
The tutorial will address both theoretical and specific technical concepts encountered in the analysis, measurement and design of linear noisy circuits. Although the material to be presented can be found in many published books and papers, it is usually broadly scattered and not necessarily presented in orderly sequence. It will cover tutorial exposition of some key physical and network theoretic ideas as applied to practical models, circuits and measurement methods. It is therefore addressed to those interested in developing a good understanding of noise in microwave devices and circuits. The subjects to be covered are as follows:
1) Physical sources of noise
- 1/f noise
- Noise representation of 1-port networks
3) Noise measurement
- Y-factor measurements–noise sources and calibrations
- Noise parameter measurements of two ports
- Most used methods of noise parameter measurements
- Noise standards and accuracy of noise measurements
5) Low-noise amplifiers
- Fundamental considerations
- Designs for simultaneous noise and gain match
2) Noise analysis of linear networks
- Twiss’ theorem
- Noise parameters of passives
- Noise representation in multiport networks; noise parameters
- Noise figure, noise temperature, noise measure, Friis’ formula
4) Noise models of microwave transistors
- Field effect transistor noise models
- Bipolar transistors (including HBT) noise models
- Allowable values of noise parameters for transistors
- Experimental validation
- Limits on allowable values of noise parameters of transistors
- Limits on achievable noise temperature of field effect transitors
6) Miscellaneous topics (time permitting)
- Mixer as linear noisy two port
- Introduction to radiometry
