This article highlights the effect of superstrate material on a high-gain antenna using array of parasitic patches for wireless applications. The antenna structure consists of a microstrip antenna, which feeds an array of square parasitic patches fabricated on a ceramic or FR4 superstrate. The patches on a superstrate are suspended in air at k 0 /2. The spacing between parasitic patches and patch dimensions decrease with dielectric constant and, thus, a compact antenna with almost same gain can be designed with high dielectric superstrate. The structures with 5 Â 5 array of square parasitic patches provide a gain of 17.5 dB on infinite ground plane in both the cases but the array dimension is 55 Â 55 mm 2 in ceramic as compared to 115 Â 115 mm 2 Antenna with ceramic superstrate on finite ground requires 25% less ground plane size as compared to FR4. Structure with FR4 superstrate is designed, fabricated, and tested. The measured VSWR is <2 over 5. 725-5.875 GHz frequency band. The antenna with 5 Â 5 array of square parasitic patches provides a gain of 18.0 dB with 92% efficiency, SLL of À18.4 dB, and front to back lobe ratio of more than 20 dB. The proposed structure can be packaged inside an application platform.

“…It is well know that high directive antennas play an important role in many practical applications. Many conventional efforts have been made to improve the antenna directivity such as parasitic patches, array of patch antennas, and parabolic reflectors [14][15][16]. Unfortunately, the aforementioned approaches suffer from large sizes, design methodology, complex feeding network and fabrication processes, particularly in the high frequencies.…”

Abstract-In this paper, a new high performance slotted waveguide antenna incorporated with negative refractive index metamaterial structure is proposed, designed and experimentally demonstrated. The metamaterial structure is constructed from a multilayer two-directional structure of electrically split ring resonator which exhibits negative refractive index in direction of the radiated wave propagation when it is placed in front of the slotted waveguide antenna. As a result, the radiation beams of the slotted waveguide antenna are focused in both E and H planes, and hence the directivity and the gain are improved, while the beam area is reduced. The proposed antenna and the metamaterial structure operating at 10 GHz are designed, optimized and numerically simulated by using CST software. The effective parameters of the eSRR structure are extracted by Nicolson Ross Weir (NRW) algorithm from the s-parameters. For experimental verification, a proposed antenna operating at 10 GHz is fabricated using both wet etching microwave integrated circuit technique (for the metamaterial structure) and milling technique (for the slotted waveguide antenna). The measurements are carried out in an anechoic chamber. The measured results show that the E plane gain of the proposed slotted waveguide antenna is improved from 6.5 dB to 11 dB as compared to the conventional slotted waveguide antenna. Also, the E plane beamwidth is reduced from 94.1 degrees to about 50 degrees. The antenna return loss and bandwidth are slightly changed. Furthermore, the proposed antenna offered easier fabrication processes with a high gain than the horn antenna, particularly if the proposed antenna is scaled down in dimensionality to work in the THz regime.

“…But in these cases for achieving high gain, a large number of elements are needed, which not only increases the size of the antenna but also decreases its efficiency (Lafond et al, 2001), (Kärnfelt et al, 2006) & ( Soon-soo oh et al, 2004. It has been reported that for high gain, a superstrate layer can be added at a particular height of 0.5 0 above the ground plane (Choi et al, 2003) , (Menudier et al, 2007) & (Meriah et al, 2008).…”
