In order to improve the bandwidth of the traditional patch antenna, a new antenna sensor based on the U-slot antenna was designed in this paper. The electromagnetic simulation software Ansys-HFSS was used to analyze the impact of the antenna parameters, and short circuit loaded half U-slot antenna with a slot ground plane was designed at last. The main bandwidth of the antenna sensor ranges fro...

This paper presents a compact dual-band slot antenna for 2.4/5 GHz WLAN applications. The radiating elements of the proposed antenna are composed of a square ring slot and a circular ring slot, operating at 2.4 GHz and 5 GHz bands respectively. The antenna size is very compact (40 mm × 40 mm × 1 mm), and can be integrated easily with other RF front-end circuits. It is demonstrated that the prop...

High gain broadband plasmonic slot nano-antenna has been considered. The theory of plasmonic slot nano-antenna (PSNA) has been developed. The analytical model takes into account also the electrical field inside the metal due to imperfectness of metal in optical range, as well as numerical investigation based on finite element method (FEM) has been realized. It should be mentioned that Yagi-Uda ...

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...

Abstract—A compact wide-slot antenna fed by microstrip-line for wideband operation is proposed and studied. The proposed antenna consists of a microstrip-fed line and a wide rectangular slot with a reverse L-shaped slot. The proposed antenna resonates the 10-dB bandwidth from 2.17 GHz to 6.25GHz, and these frequency bands cover the standard IEEE 802.11b/g (2.4–2.485 GHz) and IEEE 802.11a (5.15–...

In this paper hexagonal patch shape with hexagonal slot, ultra wideband antenna is proposed. The total dimensions of antenna are 55×43.5mm. Sides of hexagonal patch are taken 13mm each and hexagonal slot sides are taken as 3mm each. The antenna resonates at two frequencies in ultra wideband range (UWB). There is enhancement in BW in upper range ultra wideband frequency from 6.2 GHz to 8.2GHz du...

Different fractal based structures have been widely used in numerous antenna designs for various applications. In this paper, a printed slot antenna has been introduced as a candidate for use in the dual band wireless communication applications. The antenna slot structure is in the form of a Sierpinski gasket of the first iteration. The antenna has been fed with 50Ohm microstrip transmission li...

This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

In this paper dual band aperture coupled Circularly Polarized (CP) C-Slotted antenna with a small frequency ratio exited through a single feed is proposed for GPS application. The optimized design of CSlot antenna has been validated using IE3D Electromagnetic wave simulator. The C-slot is asymmetrical about the centre of the antenna. The antenna parameters can be optimized by changing the physi...
