• Abstract:

  The Industrial Scientific and

  Medical band in 60 GHz (57 GHz to 64 GHz)

  is being proposed to high data rate wireless

  transmission requiring antennas with efficient

  design. In this paper we present an on-chip array

  aperture couple antenna, using Koch fractal

  geometry. The proposed antenna is composed

  by a transmission feed line, an aperture

  and patch element built in aluminum with 2

  micrometers of thickness lying on two layers of

  silicon with height of 200 micrometers. Those

  dimensions were calculated according to the

  effective wavelength for resonance frequency

  at 60 GHz in order to match at 50 Ohms. The

  proposed antennas have been simulated using

  the ANSYS software, and the results show

  an omnidirectional radiation pattern, with half

  power beamwidth greater than 124 degrees,

  gain of 16.7 dBi, and polarization close to the

  circular polarization with axial ratio less of 2.22.
