Abstract :
Three designs are described for small-sized unsuperdirective antennas in whose near zone there is an area with a small field. This area is formed as a result of mutual suppression of various sections of the antenna radiation. Antennas with a "dark spot" in the near zone are necessary for electromagnetic compatibility maintenance and for the development of mobile telephones, which do not create large fields in the user\´s head, i.e. ecologically harmless. The formation of a "dark spot" in the near zone does not distort the antenna pattern.
