In this paper, a new compact multiband patch microstrip antenna design is presented as a candidate for use in modern multi-functions communication systems. The proposed antenna design is fractally generated using Koch fractal curve geometry applied to the conventional square microstrip patch antenna. Antenna structures resulting from the successive iterations in the proposed fractal generation ...
This paper proposes the rectangular microstrip patch antenna suitable to operate in different frequency bands. The rectangular microstrip patch antenna is designed and simulated using IE3D simulation software. The result obtained shows that the designed antenna is suitable for operation in four different frequency bands with bandwidth of 6.90%, 2.33%, 12.02% and 2.74% .The resonating behavior i...
In this paper we show the triangular geometry of the microstrip patch is one of the mostcommon shapes having a wide range application ranging from circuit elements to modernwireless antenna. In this paper we compare Cslot microstrip antenna an slotted equilateraltriangular microstrip antenna. Recent survey of open literature shows interesting developmentof this patch as novel ci...
In this paper a novel structure of metamaterial is proposed in order to miniaturize a rectangular microstrip patch antenna. The metamaterial is composed of two nested split octagons which are located on a 10 mmx10 mm Rogers RT/duroid 5880 with 0.7874 mm thickness and dielectric constant of 2.2. A 3X5 array of such metamaterials is placed on the patch antenna substrate. By using this metamateria...
The increasing demand in portable devices with wireless connectivity provides a challenge to design a RF front antenna. Microstrip patch antennas are widely used because they are of light weight, compact, easy to integrate. However the serious problem of patch antenna is their narrow band due to surface losses and large size of patch for better performance. So for the antenna miniaturization an...
the design of microstrip antenna for improved bandwidth and directive gain is a challenge for researchers. This paper proposes the design of a Microstrip Square-Patch antenna with enhanced Bandwidth and Directive Gain. The design and simulation of this antenna has been done with the help of Ansoft HFSS. The simulated results give significant improvement in terms of directive gain and bandwidth....
In this paper, we propose a novel microstrip antenna for operating over a three frequency bands, covering the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5GHz WiMAX bands. The proposed antenna occupies an area of 30 mm 40mm, when printed on FR4 substrate (εr=4.4, h=0.8mm). The antenna comprises of a triangular patch section, L-shaped parasitic elements on the edges of triangular patch and a 50Ω micros...
A single layer monopole hexagonal patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting two equal slots which are the combinations of two triangular and one rectangular slot at the upper right and lower left corner and middle point symmetrical Y-junction slot located from the conventional microstrip patch antenna. Compared to a conventio...
This paper presents the increase in bandwidth of a Microstrip Antenna using a simple slotted structure fed by Microstrip line. The main aim of proposed work is to obtain a large bandwidth antenna with reduced size. The proposed microstrip antenna has a wide bandwidth covering the range from 1.806-2.978 GHz. By using simple Microstrip Line feed wide bandwidth of 48.99% has been achieved. The pro...
Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system’s printed circuitry. In this project, a 2.4 GHz circular polarization microstrip antenna is designed, constructed and measured. The selected microstrip antenna is a dual –fed circular polarized microstrip antenna. The antenna consists...
