FIELD: physics, communications.SUBSTANCE: invention relates to broadband microstrip antenna systems with low sensitivity to multibeam reception. The broadband microstrip antenna system has an earthing plane comprising: a first surface having a first cross dimension; and a cavity filled with air, wherein the cavity has a second surface having a second cross dimension; and a side wall surface having a first height; and a radiating element having a third cross dimension, wherein the radiating element is placed crosswise within the cavity, has a second a second height from the first surface, wherein the second height is greater than zero but not more than 0.05?, where ? is the wavelength in free space for the broadband microstrip antenna system, and has a third height from the second surface, and is separated from the earthing plane by air; and a conductor connected to the radiating element and configured to feed electromagnetic signals into the radiating element.EFFECT: obtaining a small-size broadband microstrip antenna system with a wide bandwidth and low sensitivity to multibeam reception.17 cl, 18 dwg |
