ABSTRACT
This chapter describes electromagnetics, microwave engineering, wearable systems, and antenna measurements. Antenna measurement facilities are expensive. Some of these drawbacks can be solved by near field and indoor measurements. The phantom represents human body tissues. It contains a mix of water, sugar, and salt. The relative concentration of water, sugar, and salt determines the electrical characteristics of the phantom environment. The output power and linearity measurement setup consists of a sweep generator, device under test, and a spectrum analyzer or power meter. The power input protection measurement setup consists of a sweep generator, power amplifier, device under test, attenuator and spectrum analyzer or power meter. The switching time measurement setup consists of a sweep generator, device under test (DUT), detector, pulse generator, and oscilloscope. The pulse envelope can be observed on the oscilloscope. Switching time can be measured using the oscilloscope.
