In order to reduce the minimum antenna measurement distance, the aperture reduction is needed. While the aperture reduction will cause the gain of the antenna reduced. The method of loading the elongated dielectric rod on the rectangular waveguide can remarkably improve the gain of the antenna without increasing the antenna aperture. A simulation study was carried out on the antenna with a dielectric...
A wideband THz H-plane dielectric horn antenna based on silicon (Si) technology is proposed in this paper. The antenna can be integrated with the planar structure circuit and the dielectric ridge waveguide. To fabricate the proposed antenna, the deep reactive ion etching high-resistivity Si fabrication process is used. The size of the proposed antenna is $3.13 \times 4 \times 0.1$ mm3. The operating...
This paper introduces an in-house far-field THz antenna measurement system. The antenna measurement system covers the bands of 220–325 GHz, 325–500 GHz, 500–750 GHz and 750–1100 GHz.
In this paper, we inter-compare the antenna efficiency obtained from two different reverberation chambers using non-reference antenna methods in order to assess the chamber effects on the methods. A directional antenna and an omni-directional antenna are used for this study. It is found that the difference between the results is relatively small with a maximum up to around 10% within their operational...
