Abstract: A novel design of micromachined horn antenna is presented. Horn excited with a quasi-Yagi antenna. In this paper micromachining process of this antenna, and simulation results of a horn structure operate around 330GHz using Agilent High Frequency Structure Simulator (HFSS) software is presented. The results indicate a gain around 10dB, directivity 10.5dB and resonant dipole impedance 48.3Ω for horn antenna. The micromachined horn antenna is a high-efficiency antenna suitable for applications in millimeter-wave imaging systems, remote-sensing, and radio astronomy.
