In this article, a novel substrate integrated waveguide (SIW) is used to design multifrequency cavity‐backed log‐periodic slot antenna. The proposed design has three layers of cavity‐backed structure namely feeding SIW, resonant SIW, and log‐periodic slot SIW in order to achieve low loss, high gain, and easy integration with high‐frequency components. The proposed structure also includes an inductive window slot to couple the energy from feeding SIW to resonant cavity. The experimental results shows that 10‐dB impedance bandwidth of 870 MHz (7.9%), 390 MHz (2.7%), 410 MHz (2.5%), 310 MHz (3.9%), and 420 MHz (2.2%) are obtained at resonant frequencies 11.25 GHz, 14.25 GHz, 15.95 GHz, 16.9 GHz, and 19.15 GHz, respectively. Also, a realized gain of around 18.24 dB is obtained at the bore sight direction. Moreover, the simulated and experimented results are in good agreement and make the antenna more suitable for Ku and K band applications.

“…Generally, arrays based on the SIW structure can be divided into two groups: series-feed arrays [10]- [13] and cavity-backed arrays [14]- [19]. These arrays reported in the literature have excellent radiation performance but with significant disadvantages when expanding to large-scale arrays.…”

A 16×16 substrate integrated waveguide (SIW) cavity-backed array antenna is proposed in this paper. The array consists of two layers. The top layer employs novel SIW based sub-arrays with a compact size. The bottom layer is an 8×8 SIW corporate-feed network to feed the sub-arrays. The Chebyshev amplitude weighting is employed in the feed network, which substantially reduces the side lobe level. The array antenna is fabricated using low cost printed circuit board technology. The experimental results show that the proposed array antenna has a large bandwidth of 15% from 18.5 GHz to 21.5 GHz with a peak gain of 29.1 dBi at 20.5 GHz. Across the entire band, high radiation efficiency above 62% and a low side lobe level below -17 dB are realized. The design principle can be used as a guidance for large-scale planar array antenna design and the proposed antenna can be used as a receiving antenna located on the ground in satellite communication systems.Index Terms-Antenna array, sub-array, substrate integrated waveguide, Chebyshev distribution, side lobe level, high gain, large bandwidth.0018-926X (c)

“…Various shapes of patches were studied to improve the bandwidth of the microstrip antenna and achieve more than 7% impedance bandwidth in X‐band applications . Typically, the slot with a large width to length ratio has been used to enhance the operating bandwidth and gain of the patch array antenna which has been integrated with a power divider . Designing the power divider with SIW technique is a time‐consuming procedure, so SIW cavity‐backed antenna array without using individual feeding network is suggested .…”

In this article, a new arrangement of patch array antenna incorporated with cavity back substrate integrated waveguide (SIW) and stacked structure is which operating at X‐band, is presented. The proposed structure enhances the gain and bandwidth of the array antenna markedly. The prototype antenna contains a 2 × 2 patch array formation with compact feed network that helps to miniaturize the structure and improve radiation properties in antenna. The inner metallic posts inside of the antenna limit the propagation of the lower mode and therefore TM220 mode is propagated as a dominant mode. For designing of the antenna, equivalent cavity model is used, but for the final full wave simulations, it is replaced with SIW configuration. The stack layer is added to the antenna to improve its bandwidth, efficiency, and gain. The proposed antenna is fabricated on RO4003 substrate with thickness of about 0.8 mm, and total dimensions of 38 × 38 mm2 and stacked layers are etched on RT‐Duroid 5880 substrate with thickness of 1.6 mm. An acceptable agreement is obtained between measured and simulated results. The proposed antenna has 2.7% bandwidth and at the center frequency (9.01 GHz) its gain is 10.8 dBi with 95% efficiency and 25.02 dB front to back ratio. © 2016 Wiley Periodicals, Inc.
