This thesis deals with coplanar directional and hybrid couplers. Firstly, the thesis describes the theory of hybrid microwave integrated circuits with their advantages and disadvantages in comparison with other types of microwave circuits. Next, the thesis deals with basic microstrips and individual types of coplanar strips and waveguides are also more closely analyzed. The thesis also explains a theory of directional and hybrid couplers and analyses particular kinds of directionality and attributes of the real directional couplers. The following chapter shows a method of design of a few coplanar directional coupler types. Attributes of the types are then verified in CST Microwave Studio. The last chapter includes measured parameters of the couplers and their comparison with the theoretical values from the previous part. The next aim of the thesis is to create laboratory tasks which deals with coplanar directional couplers. The laboratory task is found in the appendix.
