Received May 23, 2019 Revised Nov 24, 2019 Accepted Dec 21, 2019 Keywords: Band-pass Filter Multi-layer hairpin Reduced size Size reduction ABSTRACT This paper presents a reduced size microstrip five poles hairpin band-pass filter using three-layers structure for Ku-band satellites application. For the last decade, the subject concerned significant interest and multilayer structure methods have been introduced in order to reduce the size and increase the bandwidths of the microstrip filters [16-24]. [...]the core material that contains the upper and lower resonators is constructed as the third layer of the PCB board. [...]this section will introduce some parametric studies and analyses that have been carried out using the sweep parametric function of the electromagnetic simulation software CST Microwave Studio.
