Design of high-permittivity ceramic UHF microstrip filter for a space application

The miniaturization of embarked devices remains a major concern in many applications and in particular in the space domain. Alternative solutions based on the use of ceramic materials with very high dielectric permittivity, enhanced electric properties and high temperature stability are worth being investigated. This paper presents the design of a 720 MHz central frequency microstrip bandpass filter. This filter use a ceramic with a relative permittivity ¿r = 90. Simulations, and measurements over a large range of temperature are presented.
