Abstract
A squint-less slot-antenna array (2D), built on a single substrate integrated waveguides (SIW), is shown. The effort needed for designing a suitable feeding network in SIW technology is justified in view of obtaining lightweight, low profile and low-cost antennas for many applications, including direct broadcast satellite. A proper definition of a “H”-shaped sub-array, made of four slot-pairs, is used to improve the input matching over a wide band. This choice allows remarkable simplification of the fabrication process, as the slots are cut directly in one of the metallic planes forming the SIW.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
