“…Since the antenna has no frequency-sensitive elements, so performance bandwidth is limited only by the feed waveguide. However, ultrabroadband hornreflector antennas are rarely mentioned in the literature, [7][8][9][10][11][12] use of rectangular waveguides is usually required, resulting in a bandwidth of 1.5:1. In Zhu et al, 7 an aperture-shared all-metal parabolic antenna operating at the C-and Ka-bands is designed for the sub-6-GHz and the mm-wave applications.…”

In Cheng et al, 8 Tekkouk et al, 9 Yan et al, 10 and Klionovski et al, 11 millimeter‐wave multibeam antennas with substrate‐integrated waveguide (SIW)‐based horn‐reflector feeding are presented. The few studies presented are conical, pyramidal, and SIW‐based horn‐reflector antennas.…”

In this paper, an ultrabroadband linear array in which horn‐reflector antennas are used as radiating elements by adding a central ridge to the rectangular waveguide, leading to an increased bandwidth of 3:1. With a reflector embedded in the H‐plane sectoral ridged horn, a desired narrow beam can be easily achieved. Moreover, due to the compact enclosed structure, the proposed reflector array can not only eliminate the illumination loss but also significantly reduce size compared with those of conventional array‐fed parabolic cylinder antennas. Good agreement between the calculated and measured results is obtained, showing that the proposed antenna array has a high aperture efficiency of about 80%, a ±45° scanning range in the E‐plane and 5° beam coverage with low side lobes in the H‐plane within the frequency range of 6–18 GHz.

“…Nevertheless, the above-mentioned methods are either unsuitable for waveguide structures [23] or complex to extract the parameters from the equivalent circuits. In [23][24][25][26][27], simpler methods by introducing the other slot or patch placed no more than a quarter period far away from the basic slot or patch to suppress the OSB was reported. But it is hard to be used for longitudinal slots longer than a quarter period on the waveguide structure.…”

Periodic leaky-wave antennas (PLWAs) suffer two main issues limiting their scanning ability. The first one is n= −2 spatial harmonic radiation, generating high grating-lobe levels. In this paper, a simple technique by introducing glide-symmetry structure to the PLWA is analysed and used to reduce n = −2 space harmonic level and enhance n = −1 harmonic radiation, subsequently. The other issue is open-stopband (OSB), preventing PLWAs from scanning through broadside. By analysing the ABCD matrix of the cascaded equivalent circuit for the unit cell, a conjugate match condition to counteract the susceptance of the radiation element to suppress the OSB is obtained, which is simple without extracting any parameters. A half-mode substrate integrated waveguide-based prototype is designed and manufactured to demonstrate the proposed methods. The measured results show that the proposed antenna achieves gain fluctuation lower than 1 dB and sidelobe level less than −12 dB, indicating OSB and n = −2 harmonic suppression well, which demonstrates the validity of the proposed method.
