A novel technique is introduced to improve the directivity of the E-plane pattern of substrate integrated waveguide (SIW) horn antennas. While the H-plane directivity of a SIW horn antenna is good, SIW horns have a wide E-plane radiation pattern due to the thin substrates of SIW circuits. Increasing the substrate height to improve the E-plane half power beam width (HPBW) makes it difficult to fabricate...
