Ridge Gap Waveguide Based Array Antenna For 5g/wifi Applications

This paper presents an efficient antenna configurations design with low dispersion, low loss antenna with high gain. It is based on SIGW technology. The feeding network is composed of two layers, the top layer comprises the top ground implemented on dielectric material Rogers RO4003C and the bottom layer includes the ridge and the surrounding periodic structure of vias implemented in dielectric material Rogers RO4350B. The ridge is branched to form power divider to feed the antenna array. the two slot antennas are implemented on the top ground of the top layer. It is analyzed using the Finite Deference Time Domain (FDTM) analysis (CST microwave studio) and fabricated using PCB technology. A triple band is achieved for WiFi application. It operates at 5.9, 6 and 6.1414 GHz with reasonable gain. The structure is fabricated and measured which finding reasonable agreement between both results. This antenna can also be used for energy harvesting at these bands, once connected with a rectifying circuits.
