Through-Wire Microstrip-to-Empty-Substrate-Integrated-Waveguide Transition at Ka-Band
The advantages of the Substrate-Integrated Waveguide (SIW) in terms of low profile, integration with Swim Parts Printed Circuit Board (PCB) and low cost are maintained by the Empty Substrate-Integrated Waveguide (ESIW).Moreover, as the dielectric fill is avoided, other advantages are also added: resonators with higher quality factor and lower inser
