Ultra-wideband antenna

An antenna pattern integrated-on-chip for transmitting and/or receiving sub-terahertz and terahertz (THZ) signal& The antenna pattern comprising: a first conductor having a bi-circular structure; a second conductor having a bi-circular structure connected to the first bi-circular structure. The bi-circular structures comprising a first conductive circular lobe having a radius (Rx) and a second circular lobe having a radius (Rc), such that said Rx≥Rc. The first bi-circular and the second bi-circular characterized by at least one port thereby, having an area of intersection between the first bi-circular and the second lei-circular, forming an ultra-wideband (UWB) frequency response of more than about 100% bandwidth.
