A sectionalized microstrip antenna relates to radio communications and may by used in land and satellite radio communications systems. The antenna comprises two sections, an insulating base, a conducting screen, with a first section being arbitrary shape and dimensions commensurable to wave length. A second section has the same form and design that first section has. A coaxial feed is laid cut-short from end of second section to middle of a gap between first and second sections. An outer conductor of the coaxial feed is connected to a conducting screen at least in one point near of a second section and connected along all length to second section surface. A central conductor of the coaxial feed is connected to first section near the gap between first and second section. The conductor has a diameter which equals to diameter of outer conductor of the coaxial feed laid cut-short from end of the second section to middle of a gap between first and second sections symmetrical to the coaxial feed. The conductor is connected to the conducting screen at least in one point near end of first section and connected to along all length to first section surface. The technical result is reduction of antenna dimensions. |
