Abstract: The present invention discloses a dielectric filter with multilayer resonator, including a dielectric block, a plurality of multilayer resonator formed in the dielectric block, wherein each multilayer resonator is in a column shape extending in a first direction into the dielectric block and is formed of multiple metal layers paralleling and overlapping each other in a second direction, and vias extend in the second direction and connecting the metal layers in each multilayer resonator, and a ground electrode connected to the ground terminal of each multilayer resonator.

Abstract: An antenna includes a ground layer, two polarization signal feeding terminals disposed on the ground layer, two polarization structures, four coupling metals and four radiating metals. The first polarization structure includes a first extending portion electrically connected to the first polarization signal feeding terminal and extends from a first channel to a second channel in a first direction over the ground layer. The second polarization structure includes a second extending portion electrically connected to the second polarization signal feeding terminal and extends from a third channel to a fourth channel in second direction over the ground layer, wherein the first extending portion crosses the second extending portion in a non-contact manner to define four regions. The four coupling metals are disposed on the first through the fourth regions, respectively. The four radiating metals are disposed on the first through the fourth channels, respectively.
