Abstract EN
A cavity-backed angled-dipole antenna is proposed for millimeter-wave wireless applications.
The angled-dipole radiator is built on both sides of an RT/Duroid 5880 substrate ( ε r = 2.2 ) and fed by a parallel-plate transmission line.
The cavity-backed reflector is utilized to improve the radiation characteristics of the angled dipole, such as gain, back-radiation, symmetric pattern, and similar 3 dB beamwidth in the E - and H -planes.
The design, with a cavity aperture of 0.5 λ 28-GHz × 0.5 λ 28-GHz , results in a S 11 < - 10 dB bandwidth of 26.7–30.6 GHz, a gain of 6.6–8.0 dB, and a similar 3 dB beamwidth of approximately 70° for both the E - and H -planes.
Eight-element linear arrays with the proposed antenna having a center-to-center spacing of 5.6 mm ( 0.52 λ 28-GHz ) are characterized, fabricated, and measured.
By applying nonuniform power distribution across excitations, the array achieves a scan angle up to 40° and a sidelobe level below −15 dB.
