V-band (57–66 GHz) planar antennas for WPAN applications

In this paper we present two planar V-band antennas for wireless personal area networks applications. Both of them are implemented on conventional single layer substrates that can serve as packaging for integrated transceivers. Antennas on low- and high-permittivity substrate are investigated and their performances are discussed. The antenna on low-permittivity substrate is shown to have gain higher than 10 dBi and return loss better than 10 dB in 57-66GHz frequency band. The other antenna is demonstrated to have similar characteristics only in two sub-bands of the frequency range due to poor manufacturing quality and higher order mode excitation.
