“…This proposal validates the principle of getting different beam-tilts, by essentially switching the slot associations, without using millimeter waves phase shifters. A recent study using the same fixed frequency beam scanning principle applied to a 2 × 6 array antenna operating in C-band was reported in [18], which demonstrates a beam-scanning range of 25 • (from 34 • to 59 • ). The main advantage of this work is that it's based on fewer radiating elements, and has a wider beam scanning range of 66 • (from −33 • to +33 • ).…”

A novel reconfigurable slotted leaky-wave antenna (LWA) based on a substrate integrated waveguide (SIW) with a fixed-frequency beam-steering capability is presented in this paper. For improved compactness, the structure is based on a SIW technology with rectangular slots fed by associated coupling with plated-through holes (PTH).This represents a new feeding method for etched slots in SIW antennas. Each via is loaded with a pin diode on both sides frontend of the waveguide. The pin diodes are tunable by adjusting the DC bias voltage, which results in beam scanning at a fixed frequency of around 27 GHz. Thus an electronically controlled steerable SIW antenna has been designed and experimentally verified that the radiation angle varies from −33 • to +33 • .

“…CSIW structure enables tunable leaky-wave antennas, and a beam scanning antenna using an electronically controlled LWA based on a CSIW was recently proposed [20]. In order to reduce the length of the quarter-wavelength open-stubs, a half-mode CSIW structure utilizing bent (or fan-shaped) quarter-wavelength open-stubs was recently proposed [21], however, the design suffers from drawbacks such as small scanning angle range, complex structure and fabrication, as well as low gain.…”

We propose a bent corrugated substrate integrated waveguide (BCSIW) structure that can be used to design a high gain leaky wave antenna (LWA). The design removes the need for a metallic via fabrication process needed for standard substrate integrated waveguides (SIW) and displays superior performance to previously reported structures. We use simulations to compare the performance of the proposed BCSIW LWA to equivalent standard SIW and corrugated SIW (CSIW) structures, as well as experimentally characterize a fabricated BCSIW LWA. Simulation results show that the BCSIW structure can help improve the impedance bandwidth of a slotted LWA by about 14.7% while still maintaining high gain (about 13.2-17.4 dBi) as compared to an LWA based on a CSIW structure. Measurement results indicate that the proposed BCSIW LWA has a wide impedance bandwidth (32.6%) and a high peak gain (12-16.2 dBi) throughout a large frequency range from 22 to 29.2 GHz with a large beam angle range from −69 • to −10 •. INDEX TERMS Leaky-wave antenna (LWA), substrate integrated waveguide (SIW), bent corrugated, low-cost.

“…Switching the diodes led to the electric beam-scanning. The antenna scanned from 34 ⁰ to 59 ⁰ at 5.8 GHz with a peak gain of 12.4 dBi [105]. Implementing sets of varactor diodes in rectangular ring slots on a corrugated SIW LWA resulted in a 72° beam-scanning range at 4.5 GHz, as shown in Fig.…”

A comprehensive survey of the reconfigurable leaky-wave antennas (LWAs) is made in this paper. Beam-steering and unique radiating features of LWA are highlighted particularly. Therefore, radiation mechanism of different types of LWA, including uniform, quasi-uniform, periodic, and metamaterial LWAs are discussed in detail. The guiding structures for realizing LWAs, namely microstrip, waveguide, substrate integrated waveguide (SIW), and half-mode SIW (HMSIW) are investigated as well. Basic concepts of electronic beam-scanning LWAs are also introduced, and several state-of-the-art reconfigurable LWAs are studied thoroughly. The investigated reconfigurable LWAs are suitable for beam-scanning applications due to their compactness, ease of implementation, reasonably high gain, and relatively wide beam-scanning range, as will be demonstrated through this comprehensive review.
