A 60 GHz Wide-Angle Scanning Planar Phased Array Antenna in Triangular Lattice

A 60 GHz wide-scanning planar triangular-lattice phased array based on magnetoelectric (ME) dipole element is presented in this paper. The parasitic patches are introduced to the two sides of the ME dipole to strengthen the radiation in low-elevation region so as to broaden its half power beam width (HPBW). The simulated results shows that the proposed antenna element possesses a 3-dB beamwidth of over 110° in the two planes within the operating frequency band of 59–64 GHz. Based on this antenna element, an eight-element phased array in triangular grid arrangement is designed and simulated. As results, the main beam can scan from -60° to 60° in both E- and If-planes, and the maximum gain of the antenna array is 15 dBi when the beam points to the boresight. The proposed planar phased array is very potential to applied in V -band wireless communication systems.
