Hollow Waveguide 32 × 32-Slot Array Antenna Covering 71–86 GHz Band by the Technology of a Polyetherimide Fabrication

Integrated-EBG Ridge Waveguide and Its Application to an E-Band Waveguide 32×32 Slot Array Antenna

“…(c) S-parameters for the 1-to-4 power divider realized by the proposed gapped ridge waveguide with cross-shaped groove EBG structure. symmetrical metallic blocks will suppress the unwanted higher mode of the original rectangular backed cavities, while the four rectangular metallic bricks are placed just directly beneath each radiation slot which can improve the bandwidth performance of the radiator [18]- [20].…”

“…A kind of thin planar slot array antennas has been achieved based on conventional waveguide technology [18], [19], and they are high efficiency without dielectric losses [20]. However, the required manufacturing tolerances for the multilayer welding assembly process become very strict as the operating frequency increases.…”

E-Band Full Corporate-Feed 32 × 32 Slot Array Antenna With Simplified Assembly

“…In contrast, the full corporatefeed array antenna exhibits a wider bandwidth. MmW full corporate-feed slot array antennas have been reported in [9][10][11], [15][16][17][18][19][20][21]. In [17], a W-band slot array antenna with fractional bandwidth (FBW) of 21% (85 -105 GHz) and a peak gain of over 30 dBi was presented.…”

“…In [17], a W-band slot array antenna with fractional bandwidth (FBW) of 21% (85 -105 GHz) and a peak gain of over 30 dBi was presented. An E-band hollow-waveguide full cooperate-feed 32×32-slot array antenna using polyetherimide fabrication was introduced in [18]. The operating band covers from 71 to 86 GHz with a peak gain of over 37 dBi.…”

High-Performance E-Band Continuous Transverse Stub Array Antenna With a 45° Linear Polarizer

“…Millimeter-wave (mmW) E-band (71-76 and 81-86 GHz) has been allocated for multi-Gbps point-to-point wireless links [1], [2]. Wideband, high-gain planar array antenna with lower SLLs and cross-polarization are highly desired in fixed radio links, as specified by ETSI or FCC.…”
