60 GHz dipole antenna for short range indoor communication systems

This paper presents a V-band dipole antenna designed on a planar substrate. The antenna is fed by a double-sided parallel microstrip (DSPM) transmission line connected to a grounded coplanar waveguide (GCPW). The center frequency of the antenna is set to 60 GHz. In the proposed antenna structure, input impedance can be matched by simply adjusting the width and length of the DSPM. The designed dipole antenna exhibits more than a 10 GHz bandwidth (55~65 GHz) and high radiation efficiency of greater than 90%. The antenna also provides a low cross polarization level and supports uniform radiation within the entire operating bandwidth. In a full wave EM simulation, the antenna achieves a gain of approximately 6 dBi throughout the bandwidth.
