“…Height of antenna is less than λ 0 /40, which is far less than that of conventional metallic cavity backed antenna. Measured results such as 153 MHz bandwidth (6.4%) and 6.1 dBi peak gain are better than previous works [3] [4]. Proposed array antenna has advantages such as easy fabrication and convenient integration with planar circuit, high gain, low profile, low loss, good radiation direction, which is fit for ISM 2.4 GHz base station application.…”

This paper present a jagged edged slot array antenna backed by SIW cavity for 2.4 GHz base station. Rectangular slot cut on the cavity back face adds jagged edge, which reduces the size, improves impedance matching and broadens the bandwidth. Low loss GCPW is used for realizing 3-dB Wilkinson power divider to excite elements in TE 101 mode. The measurements show minimum 10-dB return loss bandwidth of 6.4% and 6.1 dBi peak gain, which are better than previous works. Proposed antenna has advantages such as easy fabrication and convenient integration with planar circuit, high gain, low profile, low loss, good radiation direction, which is fit for ISM 2.4 GHz base station application.

“…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 performance of cavity backed patch antenna surrounded by dielectric material (coating) is degraded severely due to generation of surface waves.…”

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.

“…To eliminate the back side radiation, cavitybacked slot antennas with high-radiation performances appear to be more amenable [10,11]. By using SIW structures, the same radiation performance of conventional cavity-backed slot antennas can be achieved along with the advantages of low profile, ease of fabrication and compatibility with planar integration [12,13]. The SIW technology is suggested as an alternative technique to facilitate the low-cost implementation of waveguide-like components using a standard PCB technology [14,15].…”

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.
