“…In some frequency points, the difference is nearly 10°. To improve the antenna gain, it has been shown previously that the HPBW in the E-plane could be narrowed by the following methods, such as increasing the cavity wall height, or using the parasitic wires attached to the floor of the SBA cavity, which consequently, makes the gain 1-2 dB higher [14]. When www.ietdl.org the antenna gain as high as 20 dB is required, the aperture of primary reflector will be large and the whole structure will be bulky.…”

The short backfire antenna (SBA) has been widely used for mobile satellite communications, tracking, telemetry and wireless local-area network applications. A dual-polarised wideband SBA excited by a hybrid configuration of waveguide and ortho-mode transducer is described here. The bandwidth widening of the antenna is achieved by the appearance of the second resonance point, owing to the parasitic reflector suspended on the conical sub-reflector. The aperture radiation efficiency is improved according to the reshaping of primary and sub-reflector, as well as the choke device added to the primary reflector. The antenna is designed to operate within the L-band. It has a frequency bandwidth for voltage standing wave ratio ≤ 1.5 of about 8% and a maximum gain of 20 dB. Within the antenna bandwidth, the gain and the radiation efficiency have values more than 19.5 dB and 76%, respectively. The designed antenna has a simple and compact construction and high mechanical and electrical characteristics; hence, it is appropriate for the satellite communication application. The operating mechanism is investigated to explain why the SBA can obtain good impedance and radiation characteristics. A parametric study is conducted for the use of practical engineering design.

A metamaterial-enabled design enhancing decades-old short backfire antenna technology for space applications

et al. 2019

Nearly two decades of intense study have passed since the term metamaterials was first introduced in 1999. In spite of their great promise, however, metamaterials have been slow to find their way into practical devices, and examples of real-world applications remain rare. In this paper, an Advanced Short Backfire Antenna (A-SBFA), augmented with anisotropic metamaterial surfaces (metasurfaces), has been designed to achieve a very high aperture efficiency across two frequency bands. This performance is unprecedented for an antenna that has seen widespread use, but few design changes over its more than 50 year existence. The reduced weight, compact design, hexagonal aperture, high dual-band efficiency, high cross-polarization isolation, as well as low multipaction and passive intermodulation (PIM) risk make the A-SBFA ideal for spaceborne applications. This transformative design demonstrates how practical metamaterials, when applied to conventional antenna technology, can provide significant performance enhancements.
