Abstract
The first part of the thesis is the design of polarization switchable antenna at 60 GHz.The structure is formed by a patch and a coupler. When the two of coupler input ports are fed with phase difference of 90º, -90º and 180º, patch will be radiate at four different polarizations at X-direction, Y-direction linear polarizations and right-hand, left-hand circular polarizations. It will be used as a building block for polarization switchable array for better signal quality. The antenna is implement in low temperature co-fired ceramic(LTCC).We use stacking of LTCC process to design antenna and passive component in vertical architecture. The second part of the thesis shows the dielectric constants and loss tangent measurement of different types of substrates. Both TRL calibration method and ring resonator are used. Microstrip line is used as the transmission line in the measurement.
