FIELD: radio engineering. ^ SUBSTANCE: microstrip antenna comprises radiating plate and screen arranged oppositely and separated from each other, and at the edges of radiating plate (702) and screen (701) there are capacitance elements arranged in the form of two at least lengthy ribs (703) or set of short ribs (1203) bent inside space between screen and radiating plate to provide for reduction of resonant size. Various versions are proposed for making capacitance elements, in the form of bent rib or separate set of bent ribs, which provide for larger area of elements coverage from the side of screen and side of radiating plate to reduce antenna size. ^ EFFECT: development of microstrip antennas with expanded strip of working frequencies, having at the same time compact size and weight, and also development of multi-tier structure of antenna, having above-mentioned advantages with the possibility to locate printed circuit board on its radiating plate with low-noise amplifier and other elements. ^ 28 cl, 44 dwg |
