Abstract

We propose a novel patch antenna operating at 300 GHz. The antenna has a footprint of 500 μm × 500 &mum and a height of 198 &mum. The matching and radiation properties are studied. The simulation results show that the return loss (S11) is below -10 dB in the frequency range of 290.75 to 308.20 GHz and the relative bandwidth is 5.8%. At the central frequency of 300 GHz, the S11 is -16.3 dB and the gain reaches 5.34 dB. Because of the symmetry of the structure, the 2-D radiation patterns in φ=0°and φ=90° planes are almost coincident. The designed antenna has a wide -3 dBbeamwidth of 105.8° on both φ=0° and φ=90° planes.
