A novel multihorn antenna using the substrate integrated waveguide (SIW) technology is discussed in this communication. Conventional SIW-inspired horns, being the extensions of planar H-plane horn antennas, portray a fan-shaped beam, with a narrow H-plane and a wide E-plane radiation characteristics. The present design employs this feature to produce a crossed horn, in which both E-and H-plane radiations can be realized by individually exciting the two sectoral horns, while terminating the other port to a matched load. When both the ports are excited, a spot beam is realized, representing a pattern similar to that of a pyramidal horn. Such an antenna should find its potential applications in systems requiring radiation switchability/pattern diversity from a single embodiment. © 1963-2012 IEEE.
