Abstract
This paper deals with design, simulation and experimental testing of a low pass (LP) filter for Ultra Wide-Band (UWB) radar applications. The paper focuses on various technological possibilities of production that are used in the branch of UWB filters. This paper demonstrates the design of LP filter realised by the Filter Solution 2011 from Nuhertz as well its simulation done by Ansoft Designer from ANSYS. Simulated and measured results of insertion loss and return loss response of LP filter for UWB radar are presented. This paper assesses the suitability of hydrocarbon ceramic laminate substrate for the production of LP filter for high frequency (HF) area. Paper refers to the needs to be focused on the design of passive filters used in UWB radar systems with emphasis on issues of quality of transmitted signals in the HF range. It examines potential manufacturing possibility of such filter based on Low Temperature Ceramics (LTCC) technology too. The presented filter is an example of an antialiasing LP filter for particular laboratory UWB radar.
