Description
Summary:This article describes the development of a tri-band resonant slotted waveguide antenna array for millimetric-waves applications. It is based on a novel structure composed by four slots with two different lengths proper distributed on the waveguide narrowest face. Experimental results have been shown in excellent agreement with numerical simulations carried out using ANSYS HFSS. The antenna provides three bands centered at approximately 29.8, 34.3 and 37.4 GHz. Its gain varies from 8 to 10 dBi.
