This masters thesis introduces to the reader with a modern antenna type the microstrip patch antennas.
The most common types of microstrip antennas and their parameters and feeding methods are introduced in the theoretical section of this.
The thesis deals with the research of microstrip patch antennas and antenna arrays fed by a substrate integrated waveguide (SIW).

Exploiting an SIW structure for microstrip patch antenna feeding combines the benefits of both structures.
