We demonstrate an analogue to the radio frequency (RF) monopole antenna, realizable within the constraints of ubiquitous planar chip-based fabrication. Our planar design is unique in that it
circumvents a major obstacle preventing the straightforward scaling of the antenna size down to reduce its operational wavelength; namely that the semi-infinite ground plane present in the RF design, requires a three dimensional structure. Here, we show that a long nanorod oriented perpendicular to the excited antenna arm functions as a reflector, providing a means with which to realize a monopole antenna element that is compatible with planar chip-based fabrication and therefore large-scale integration.
