This paper presents a new dielectric grating antenna based on high resistivity silicon image guide technology. The radiation is due to triangular shaped (sawtooth) dielectric gratings on the both sides of the image guide. The proposed antenna has been fabricated with a low cost single mask deep reactive-ion-etching process. The proposed optimized antenna is well-matched over the W band with radiation...
This paper presents a new method for designing planar millimeter-wave antennas with optimal shape. The method is applied to dielectric antennas for high efficiency. The method simply pixelates the available space for the antenna into small boxes and then a finite-elements solver integrated with an optimization engine is used to find the pixels pattern in this finite space which satisfies the required...
