The present invention relates to a micro band short antenna with reverse emission with multilayer printed peripheral screen designed for use as component of complex multi-element arrays or alone in communication, radio-navigation, radiolocation and broadcasting equipment in the decimetre and the centimetre range. The task solved by the invention is creation of micro band short antenna with reverse emission suitable for use as component of complex multi-element arrays with high amplification coefficient and broad frequency band, with compact design and easy for printing. This is achieved by micro band short antenna with reverse emission with multilayer printed peripheral screen consisting of a rectangular metal emitting radiating element, seven round dielectric mats, common round metal base with a rectangular slit cut in it, cylindrical multilayer printed peripheral screen, small rectangular metal reflector and excitatory micro band line connected to coaxial connector. The occurrence of two resonances in the impedance characteristic of the antenna and the occurrence of impedance matching between the individual dielectric mats and the free space increase the amplification coefficient and expand the frequency band of the antenna. The antenna has high amplification and broad bandwidth, while its compact design and the printed execution make it particularly suitable for use in complex multi-element micro band arrays. |
