Terahertz Integrated Horn Antenna Based on Substrate Integrated Waveguide
摘要
This article proposes a conical horn antenna based on low temperature co-fired ceramic (LTCC) technology, and uses substrate integrated waveguide (SIW) technology to form cavities and metalized through holes in multi-layer LTCC substrates, forming a conical horn antenna structure that solves the problems of difficult processing and integration of terahertz horn antennas. The size of the antenna is 6mm × 6mm × 3.5mm. The simulation results show that the improved substrate integrated waveguide horn antenna has a gain of 16.4 dBi in the 220 GHz frequency band.
