An original architecture to generate two orthogonal circular polarizations with slotted waveguide arrays is presented in this communication. The proposed solution consists of two interleaved slotted ridge waveguide arrays sharing the same aperture and feeding a common polarizing layer represented by a dual circular polarization horn array. The radiating element realizing the linear‐to‐circular polarization conversion is made of a slot‐fed compact septum polarizer flaring into a pyramidal horn. The horn‐loaded slot model is extracted, thus allowing the synthesis of large arrays. A dual circular polarization slot‐fed horn array antenna is designed for Ku‐band operation. The two polarizations, when combined with proper phase relation, enable the tracking of two orthogonal linear polarizations. The antenna exhibits remarkable performance for both circular and linear polarization operating modes.

“…Stepped transitions consist of ridge or internal contour steps in series, which inherently offer wider bandwidth in a relatively compact size at the expense of complex design and fabrication. 10,11 In Reference 10, a coaxial to WG transition is proposed and shows RL and insertion loss (IL) around 20 dB and 0.22 dB over a 12.2% bandwidth in the back-toback configuration measurement. In Reference 11, a WG to RWG transition is designed and simulated and RL better than 15 dB in a bandwidth of 2.5 GHz is obtained.…”

This article presents a D‐band (110–170 GHz) double ridge waveguide (WG) to standard rectangular WG transition with an E‐bend near the WG end. The transition incorporates metal ridge steps as impedance transformers, resulting in a compact total size of 3.53 mm × 1.95 mm × 1 mm. Fabricated using micro metal additive manufacturing with copper in a monolithic back‐to‐back configuration, the transition demonstrates a bandwidth of 50% (105–175 GHz) with an average insertion loss of 0.72 dB and return loss better than 15 dB, respectively. Measurement results align closely with simulation expectations, with deviations attributed to fabrication and assembly errors.

“…This is because the introduction of a ridge in the waveguide cross-section reduces the waveguide width for a given cutoff frequency. This practice is quite common in contexts where a small size and a high level of integration are needed, such as dual-polarization antennas [13], transitions [14,15] and beam-forming network components [16].…”

Single-Ridge Waveguide Compact and Wideband Hybrid Couplers for X/Ku-Band Applications

et al. 2022

Hybrid couplers are important devices that combine or divide signals in various microwave applications. Wideband performance, low losses and small size are key features in most modern radar and communication systems. This paper presents a new geometry for single-ridge, air-filled waveguide quadrature hybrid couplers at the X/Ku band on a single layer using multiple pairs of slots cut on a common ridge coupling section. Bandwidth can be progressively extended by increasing the number of slot pairs. Two designs characterized by compact size and state-of-the-art performance are proposed, leading to a fractional bandwidth up to 46.88% and a maximum dimension of 1.18 wavelengths. A tolerance analysis is presented to highlight the design robustness and reliability.
