Design of 8 × 8 Slot Array Antenna based on Inverted Microstrip Gap Waveguide
Paper in proceedings, 2016

In this paper we present the design of a high efficiency corporate-fed 8 × 8 slots array antenna in the 60-GHz band. The antenna is built using four unconnected layers — bed of nails, which works as Artificial Magnetic Conductor (AMC), PCB microstrip feeding networks, groove waveguide cavity and radiation slots layer on the top. The designed antenna shows a relative bandwidth of 14.63% with input reflection coefficient better than -15 dB and an overall efficiency larger than 70% with about 26.5 dBi simulated gain between 57 and 66 GHz.
