    This paper presents a broadband nanoantenna fed by a two-wire optical transmission line (OTL). The antenna is defined by a\ncombination of a dipole and a loop, where only the dipole element is connected to the OTL. The analysis is fulfilled by the linear\nmethod of moments with equivalent surface impedance to model the conductors. Firstly, the nanoantenna alone is investigated,\nwhere the input impedance, current distribution, reflection coefficient, fractional bandwidth, radiation efficiency, and radiation\npattern are analyzed.Then, the input impedance matching of this antenna with the OTL is considered. In this case the current, near\nfield distribution, radiation pattern, and reflection coefficient are calculated for different geometrical parameters. The results show\nthat the loop inserted in the circuit can increase the bandwidth up to 42% and decreases the reflection coefficient in the OTL to\nâË?â??25 dB.
