Abstract—In this paper, the design of a multiband antenna for WLAN and WiMAX applications is proposed. The proposed antenna comprises a circular radiating patch with a pair of rectangular slits and an inverted U-shaped slot. A hexagon-shaped slot is cut on the ground plane. By adjusting the inverted U-shaped slot, a pair of rectangular slits, and a hexagon-shaped slot, three distinct resonance ...

In this paper, the authors propose a circularly polarized printed antenna combining a slot array antenna and a patch antenna, with dual-band operation. The proposed antenna has good isolation performance, is compact, and has simple configuration. This antenna is composed of two parts, a patch antenna (for Rx) on the top, and a slot array antenna (for Tx) on the bottom, respectively. The element...

A printed slot antenna fed by a microstrip line with a diamond-shaped tuning stub for bandwidth enhancement is proposed and experimentally validated. Impedance bandwidth, radiation pattern, and gain characteristics of the proposed antenna are investigated. The simulated results show that the impedance matching of the proposed rotated slot antenna is greatly affected by the dimension of the slot...

This paper shows a comparative study of Multi U–shaped slot antenna with the substrate integrated waveguide(SIW) fed patch antenna. By cutting four asymmetrical U-slots, we can make U-shaped patch antenna. Advantages of this structure are the simple feed, single layer structure, simple structure of antenna, one more degree of freedom can be achieved by the asymmetry of U-slot arm. The design gu...

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...
