Bandwidth Enhancement of A Micro strip Line Fed Hexagonal Wide - Slot Antenna Using Fork - like Tuning Stub
نویسنده
چکیده
In this paper, a printed hexagonal wide slot antenna, fed by a microstrip line with fork like tuning stub for bandwidth enhancement is proposed and experimentally investigated. The impedance, radiation and gain characteristics of this antenna are studied. Simulation and experimental results indicate that a 1.5:1 VSWR bandwidth, of about 1 GHz and 2:1 VSWR bandwidth of 1.34 GHz is achieved at operating frequency around 2.5 GHz, which is about three times larger than a microstrip line fed hexagonal wide slot antenna, with normal tuning stub, considered as reference antenna.

Bandwidth Enhancement of a Printed Slot Antenna with a Diamond-Shaped Tuning Stub
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...
متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملMultiband Slot Loaded Uniplanar CPW-fed Monopole Antenna with Asymmetrical Arms
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 ...
متن کاملDesign of Dome Shape Slot Antenna for UWB Applications
In this paper, a compact micro strip fed dome shape slot antenna for Ultra Wide Band (UWB) applications is proposed. The dome shape is obtained by rounding (blending) the corners of a hexagonal slot. To excite the slot, a micro strip feed and a rectangular shape tuning stub is used. One of the corners of the rectangular patch is chamfered while the others are blended for better impedance matchi...
متن کاملCompact CPW-fed Circular Patch Antenna for UWB Applications
In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also ado...
