Abstract :
A 2×2 LTCC horn array is presented. The antenna is based on substrate integrated waveguide (SIW) technique whereby the flare of the horn is designed in vertical steps of the LTCC layer. The proposed 2×2 horn array is fed through horizontal as well as vertical power dividers. A LTCC slab is designed as a phase corrector in front of each horn. The measured impedance bandwidth for |S11|=-10dB is about 9 GHz and the simulated gain is around 13.3 dBi at 140 GHz. The antenna is compatible with system in package (SiP) as well as providing end-fire radiation.
