Abstract :
This work presents one wideband coupled mushroom antenna by 3D-TSV based Composite Right/Left Handed Transmission Line (CRLH T-Line). The antenna has 2×2 mushroom unit-cells with rectangle loop notch on the top metal surface to form inner and outer CRLH T-Line. As a result, there are three resonance modes in one band that improves operation bandwidth. The proposed antenna is centered at 150GHz with 14GHz bandwidth, gain of 5.2dBi and efficiency of 78%. The overall dimension of the proposed antenna is 608μm×188μm upon high resistivity silicon substrate with a thickness of 80μm. The demonstrated antenna shows promising applications for sub-THz biomedical imaging.
