Miniature Filters, Diplexers and Antennas of L-Band Used in Receivers of Satellite Radionavigation System

New miniature filters, diplexers, based on low and high pass filter, and antennas for satellite radio navigation system based on low and high pass filter are presented. These devises are manufactured on ceramic substrates with different thickness and ε =40, 80, 120 by using thick-film technology where topology is formed with silver conductors by laser.In the article simulated and experimental filters, diplexers and antennas main characteristics are presented as well as a topology
