Oct 18, 2018 · To extend the bandwidth of the array, each 1×16-element linear array is separated into two 1 × 8-element arrays, which are fed by a two-way ridged waveguide divider via H-shaped slot couplings. The evanescent-mode ridged waveguide filters are integrated into a two-way ridged waveguide divider that suppresses the out-of-band signal interference.

Sep 16, 2016 · The procedure to design a waveguide slot array antenna is explained, and also the analysis model to design the element is discussed as well as the scattering matrix in connecting the equivalent circuit with a transmission line. Finally, the design examples for one-dimensional and two-dimensional arrays of the waveguide slot antennas are explained. This paper presents the full structure simulation of a parallel-plate slot array antenna panel with a designed waveguide feeding network, which operate in 9.50 GHz-9.80 GHz (T. Wang, T. Tomura, and J. Hirokawa, Intl. Symp. Antennas Proag., TA1P-1, Oct. 2019). Fig.1 shows the proposed antenna structure. The waveguide feeder with coupling slots Slotted Waveguide Array Antennas is the first comprehensive treatment of these antennas from an engineering perspective. It provides readers with a thorough foundation in applicable theories as well as hands-on instruction for practical analysis, design, manufacture and use of important types of waveguide slot arrays. A waveguide slot array antenna is mainly used for high gain flat antennas in millimeter-wave wireless communication systems due to their unique features such as lower loss in comparison with microstrip antennas, and simpler structure compared with reflector antennas.

The presently constructed edge- wall slotted waveguide array antenna has dimensions of 1800 mm  150 mm  150 mm, including the metal flare and the feed network. The array consists of seventy one regularly spaced inclined slots along the edge wall of a rectangular guide. Each excitation element has a width of 1.8 mm and a resonant length

A cavity‐backed slot antenna array using a single waveguide‐fed subarray is proposed to reduce feed‐line loss, increase radiation efficiency, and make the feed network simple. A subarray consists of 2 × 4 slot elements backed by a single cavity.

A dual-polarization corporate-feed waveguide 16x16-slot array antenna was proposed and fabricated in the 60GHz band [1]. A 32x32-slot array antenna in the 120GHz band is designed to increase the operating frequency band and the gain. II. ANTENNA STRUCTURE A. Feeding waveguide There are two feeding waveguides in the antenna for the

A novel basic antenna element for travelling-wave substrate integrated waveguide (SIW) arrays is proposed in this study. The antenna element is based on a transverse slot and newly complemented by a pair of vias used for matching and a phase shifter. By changing the geometries of the slot and the phase shifter, the amplitude and phase of a
