A novel dual  layer rectangular printed Antenna based on loop type Frequency selective surfaces with five concentric rings and I shaped defected ground structure (DGS) is designed and investigated. The deigned antenna is tested for application in C band, WiFi devices and some cordless telephones and X band radiolocation, airborne and naval radars as multiband  operational frequencies are at 5.5GHz, 6.81GHz, 9.3GHz and thus covers two wireless communication band C Band (4 to 8GHz ) and  X band (8 to 12 GHz) The bandwidth is 200MHz, 300MHz and 1GHz respectively and measured gain of this designed antenna are 2.42dBi against 5.5GHz, 2.80dBi against 6.81GHz, 6.76dBi against 9.3GHz. The proposed antenna in addition to multiband operation also exhibits minituarization.The Floquet port technique is used to analyse concentric rings. The Results comparison of proposed structure with the basic dual layer antenna resonaing at 5.5GHz  shows the patch area is reduced by 58.15% while the volume of the antenna is reduced by 81.5%.

Application Requirements

This paper explore about   the micro strip patch antenna design with a defected ground structure (DGS) for dual band operation. The intend of this paper is to design an micro strip antenna, under the frequency at 2.4 GHz and 5.2 GHz that can be utilized for BLUETOOTH and WLAN applications. The feeding technique used here is coaxial feed technique. The above said double band property can be established by etching U-slot in the ground plane. Being periodic structure slot is selected and it is imposed on ground plane. The periodic structures naturally modify the method of propagation of the electromagnetic signal passing on to the antenna. Essentially its core is to vary the parasitic capacitance and inductance of the material through which the substrate is made. This may moreover leads to the reduction in size and progress the performance of the antenna. Micro strip patch antennae are favored due to the fact that these are small in size, inexpensive, consume low power and easy to fabricate and also be designed to meet wide band application requirements.

In this paper, a compact, wideband, printed antenna is proposed for millimeter-wave fifth-generation communication systems. The proposed design is a patch antenna with a defected ground structure, in which ground plane defects are utilized to reduce resonance and achieve wideband operation. The optimized antenna dimensions are 2.5 mm × 4.5 mm with a substrate thickness of 0.203 mm. A prototype antenna was fabricated and measured to verify the performance, and it was established that the simulated and measured results were in good agreement. The measured bandwidth was approximately 6.4 GHz (26.5–32.9 GHz) with a peak gain of 5.62 dBi and an efficiency in operational bandwidth of 84%. The compactness, wide bandwidth, and decent gain suggest that the proposed antenna is a potential contender for forthcoming communication systems.
