“…With the above premises, the present design of a SIW planar antenna [2,3] with high gain, squint-less main lobe, and very wide bandwidth (10.7-12.7 GHz), for Direct Broadcast Satellite (DBS) and radar applications, is particularly challenging. In comparison with standard slotted rectangular waveguide (RWG) antenna-arrays [4], or with common satellite dishes, the achievable gain and efficiency are expected to be significantly lower, due to fabrication tolerances and dielectric losses (if inexpensive materials are to be employed) [5][6][7][8][9][10].…”

Abstract-A squint-less slot-antenna array (2D), built on a single substrate integrated waveguides (SIW), is shown. The effort needed for designing a suitable feeding network in SIW technology is justified in view of obtaining lightweight, low profile and low-cost antennas for many applications, including direct broadcast satellite. A proper definition of a "H"-shaped sub-array, made of four slot-pairs, is used to improve the input matching over a wide band. This choice allows remarkable simplification of the fabrication process, as the slots are cut directly in one of the metallic planes forming the SIW. Index Terms-Substrate Integrated Waveguide (SIW), planar slot-antenna array, Direct Broadcast Satellite (DBS).

“…This two stage process increases total fabrication cost of antenna and makes structure assembly complicated [3]. Substrate integrated waveguide (SIW) has been suggested as alternative fabrication technology for low cost implementation of waveguide-like components and antennas using standard PCB fabrication technology [4][5][6][7][8]. SIW cavity backed patch antennas exhibit same radiation performance as that of conventional metal cavity backed patch antennas along with advantages of low profile, easy fabrication and planar integration [9][10][11][12].…”

The cavity backed patch antenna embedded in dielectric coated structure is presented. The patch antenna is backed by a substrate integrated cavity. The aperture of antenna is surrounded by a thick dielectric material which acts as dielectric coating and significantly deteriorates impedance matching and radiation pattern of antenna. The radiation pattern of antenna is severely degraded due to excitation of surface waves in the surrounding dielectric coating. The proposed electromagnetic bandgap (EBG) structure in the form of via less metallic patches is placed on the surrounding dielectric coating. The EBG structure reduces the propagation of surface waves in the dielectric coating causing improvement in the radiation pattern of antenna. The input impedance matching of antenna is also improved. The simulated results are in good agreement with experimental results.

“…In principle, the waveguide metal walls could be emulated using via-holes properly spaced at about λ g /20. Utilization of SIW technology should help in reducing the cost of realizing the cavitybacked antennas [16,17]. The proposed antenna utilizes two PIN diodes that effectively change the slot's electrical length.…”

In this paper, a dual-band reconfigurable substrate-integrated waveguide (SIW) cavity-backed slot antenna 1 £ 8 linear array is presented with dual states. The proposed SIW antenna array combines the features of the conventional metalized cavity-backed patch arrays such as surface wave suppression, high efficiency with low-manufacturing cost. The basic element has been designed, fabricated and the performance has been verified in the outdoor antenna test range. Here, PIN diodes have been used as a switching device to achieve the reconfigurability with dual-band operation. A corporate feed network has been designed and integrated with the antenna to make it as a linear array.
