“…General ported antennas require complicated constructions. It is seen that although the an [10] can maintain a slightly higher gain than our proposed antenna, the volume cantly larger, and the structure is more complicated with a much higher finished antennas proposed in [7,8] have a much lower gain although with a complicated The designs in [6,9,11,14] had a smaller structure but with a lower gain.

“…The slotted waveguide array is attractive due to its compact size, planar form and ease to be fabricated based on the computer numerical control (CNC) milling technology [14]. Due to the low transmission loss feature, the traditional metallic waveguide-slot antenna arrays are applied in microwave-millimeter wireless communication systems.…”

This paper presents a waveguide–slot antenna to generate a radiation beam with high gain fed by a low-loss feeding network at 110 GHz. The proposed antenna consists of a compact eight-way power divider and a waveguide–slot array. The eight-way power divider provides equal-amplitude and alternative-phase excitation for the slot array, and each of them supports two waveguides. The integral structure is implemented by two layers with a channeled substratum and a slotted superstratum. To verify the proposed slot array, the designed array is fabricated with computer numerical control (CNC) milling and measured. The measured peak gain of the designed antenna is 32 dBi at 110 GHz. The proposed antenna with a simple structure provides a promising solution to develop high gain antenna in upper millimeter-wave and sub-terahertz (THz) applications.
