“…The state of art of antennas radiating a sectoral pattern presents only few examples of antennas in compact planar multilayer technology, since in general sinc-shaped or tapered aperture distributions are synthesized by means of horn arrays [21], horn antennas with shaped dielectric lenses [21][22][23] or EBG structures [24], and commonly reflector systems [25]. Instead, in this paper, we propose the design and optimization of a sectoral beam standing-wave slotted antenna array for surveillance applications at 76.5 GHz, following the systematic procedure explained in detail in [26] and profitably used in [27][28][29].…”

In this paper, we present the design and fabrication of a sectoral beam slotted antenna in substrate integrated waveguide (SIW) technology able to achieve a high roll-off sectoral pattern in the horizontal plane and a very narrow beam in the vertical plane, as required in surveillance applications in the band 76-77 GHz. The proposed antenna is designed and fabricated in multi-layer PCB technology, which allows to integrate both the corporate feeding network and the radiating aperture in the same planar and lightweight device. To achieve a remarkable roll-off (> 5.5 dB/deg) and a reduced ripple (< 1.5 dB), the antenna has been designed by synthesizing a sinc-shaped (uniform) aperture distribution along x-direction (y-direction). The synthesis and optimization of so tapered aperture distributions is not easy to be found in the literature, especially for planar devices. A prototype of such an antenna has been fabricated with a horizontal half-power beamwidth (HPBW) of 30 • , by embedding both the feeding network and the radiating aperture in three stacked dielectric substrates. Measurements of the prototype show a fair agreement with numerical simulations.

“…The research works carried out on L‐band or broadband horn antenna in the literature are mainly for gain enhancement, low cross polarization, and multimode . For better performances, horn antenna are loaded with dielectric to enhance the bandwidth and the low cross polarization, the use of dielectric in horn antenna was first introduced by Clarricoats et al in the late 1980s, then by Lier et al, later on other improved antennas were proposed …”

In this paper, a pyramidal horn antenna loaded with unit cell of metamaterial is proposed, designed and realized for L‐band that including terrestrial digital audio broadcasting T‐DAB, GPS, and GSM. The proposed antenna operates in the frequency range from 1.722 to 1.931 GHz. The metamaterial is fabricated on a printed circuit board as Capacitive Loaded Loop (CLL). The work aims to exhibit the advantage of metamaterial loaded inside the horn antenna in terms of the gain enhancement of the radiation pattern and the resonant frequency shift toward lower frequency. The retrieval technique used show that the constitutive parameters of the unit cell as CLL have a zero index metamaterial (ZIM) from 1.34 to 1.49 GHz and a near zero index of refraction from 1.495 GHz to 2 GHz, which is within the operating frequency of the horn antenna. The achieved results show that the total gain is improved over the frequency range. The simulation and the measurement are in good agreement.

“…In [6], a closed-form SIW horn is considered as a planar combiner/divider for a power combining amplifier, and multiple meander microstrip lines in front of the horn aperture are used to correct the phase difference. An H-plane post wall horn is used as a feed of an array of a tapered slot antenna (TSA) in [7]. The H-plane post wall horn and the TSA are vertical to each other.…”

As traditional horn antennas that could be used as feeds for reflector antenna systems, substrate integrate waveguide (SIW) horns could be used as feeds for planar antennas and arrays. In this letter, a phase-and-amplitude-corrected SIW horn by metal-via arrays is presented as a planar feeding structure. The compact SIW horn is applied to feed two antipodal linearly tapered slot antenna (ALTSA) arrays, forming sum and difference beams at X-band. The measured gain of the sum beam is 12.84 dBi, the half-power beamwidth is , the FTBR is 15.07 dB, and the sidelobe level is 20.79 dB at 10.1 GHz. The null depth of the difference beam is 44.24 dB. Good agreement between the simulation and the measured results is obtained.Index Terms-Antipodal linearly tapered slot antenna (ALTSA), array antenna, feeding system, planar horn, substrate integrate waveguide (SIW).
