Bandwidth enhancement of a rectangular monopole UWB antenna using M-shaped strip with triple band notched characteristic is presented. Antenna consists of an exciting rectangular patch with two C-shaped and one inverted U-shaped slots along with defected ground plane which is coupled with M shaped strip. By inserting slots to the rectangular patch, three notched frequency bands are achieved. A conceptual...
Bandwidth enhancement of an ultra-wide band swastika slot loaded antenna with band notch characteristic is presented. The antenna consists of an exciting rectangular patch on the front side and a partial ground plane on the backside of the substrate. A swastika shape is etched on patch, by inserting corner slots to the swastika shape, notched frequency band is improved. The simulated impedance is...
Design and analysis of an ultra-wide band antenna consisting extra radiating patch with bandwidth enhancement and band notch characteristic is presented. Antenna consists of an exciting rectangular patch on the front side and an extra radiating patch with π shaped slot on the backside of the substrate. By inserting a slot to the antenna, WLAN notched frequency band is achieved. A conceptual modal,...
In this paper a full composite fractal antenna, having a modified Sierpinski fractal antenna with 50-Ω microstrip line, used for dual band wireless applications. The S11 parameter and radiation characteristics of the antenna design indicate that a Sierpinski fractal antenna with circular slot having Dual Band frequency bandwidth from 3.8 GHz to 4.4 GHz and 4.8 GHz to 5.4 GHz to covering 5.2 GHz for...
In this paper, a double-layered frequency selective surface(FSS) superstrate was proposed. The unit cell of the proposed FSS consists of a square slot and a Jerusalem cross structure, which are printed on two sides of the substrate. It is designed on the FR4 dielectric substrate with a relative permittivity of 4.8, loss tangent 0.025 and a thickness of 1.6 mm. The proposed structure shows excellent...
A coplanar waveguide (CPW) fed semi circular disc antenna with a modified ground plane is presented. The proposed antenna consists of a semicircular radiating patch and semicircular arc-shaped ground plane. To achieve extremely wideband, two modifications are introduced. The first one is to modify the ground plane, and the second one is to insert slits near the feed point. Theoretical results show...
In this communication, the radiation performance of stacked arrangement of two modified rectangular patches is reported. The lower patch is fed through inset feed with SMA connector and the upper structure is parasitically coupled to the lower patch. Both patches have a narrow slot of different sizes and are placed one over each other. The size of upper patch is smaller than the lower patch. With...
This paper presents the design and performance of a broadband multilayered circular microstrip antenna useful for modern communication systems. This antenna has three different dielectric layers namely RO3003, Foam substrate and Glass epoxy FR-4 which are pasted together with a very thin layer of 3M adhesive transfer tape applied between the radiating patch and the metallic ground plane of infinite...
