The response of dipole nanoantennas (DNAs) studied widely in optical frequency range is sensitive to polarization of incident field. In this paper, we report the implementation of a cross nanoantenna (CNA) consisting of two orthogonal DNAs with a common feedgap and investigate its directional and polarization properties and compare them with those of the DNA. Interestingly the response of CNA is independent of polarization. We can operate the CNA in turnstile mode by using two identical light sources with cross polarization in phase quadrature. In such a case the radiation from the CNA is found omnidirectional like radio frequency turnstile antenna. We believe CNA could open new possibilities to study the novel phenomenon of light matter interaction. To the best of our knowledge, this is the first report on a turnstile antenna in optical frequencies.
