In this paper, a tapered slot antenna capable of ultra-wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon the basic tapered slot antenna by 4.72 GHz. DGS Based Coaxially Fed Microstrip Slotted Rectangular ... narrow bandwidth limitations of the simple rectangular microstrip patch antenna design in [17], the use of slotted patch geometry for improved gain performance with added multiband feature was considered. The microstrip slotted rectangular patch antenna proposed [17] offered a single band BANDWIDTH ENHANCEMENT OF MICROSTRIP LINE AND CPW-FED ... rectangular slot antennas to obtain broad impedance bandwidth along with stability of the radiation patterns. Dual resonance nature is observed in the asymmetric slot antenna and these resonances can be merged to achieve a higher bandwidth. The rectangular slot excited by microstrip line feed and CPW fed gives an impedance bandwidth Design of Microstrip Antenna with Improved Bandwidth for ...

DESIGN OF OPEN SLOT ANTENNA FOR BANDWIDTH … the rectangular stub of the open slot antenna are shown in Figure 3. From the simulated and measured results, it is obvious that the rectangular stub can improve the bandwidth performance of the open slot antenna. The bandwidth of the open slot antenna with the rectangular stub is approximately 139% from 2.57 to 14.23GHz, while Slotted rectangular microstrip antenna for bandwidth A half-U-slot-cut and rectangular-slot-cut are used in rectangular microstrip antenna to increase gain and bandwidth of antenna[6].The reverse L-shaped slot is connected from bottom of rectangular Novel Design of Microstrip Antenna with Improved Bandwidth A novel design of broadband patch antenna is presented in this paper. The broadband property of the proposed antenna is achieved by choosing a proper selection of dimensions and positions of slot and notch on the radiating patch. The bandwidth of the proposed antenna is found to be 30.5% with operating frequency band from 1.56 GHz to 2.12 GHz.

show that, bandwidth of conventional rectangular microstrip antenna can be enhanced from 4.81% ... microstrip antenna, slot patch, substrate I. INTRODUCTION
A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna. A rectangular slot antenna with improved bandwidth A rectangular slot antenna with improved bandwidth Article in AEU - International Journal of Electronics and Communications 66(6) · June 2012 with 68 Reads DOI: 10.1016/j.aeue.2011.10.008 Implementation of rectangular slit-inserted ultra-wideband ... To improve the bandwidth, rectangular slits were inserted in the tapered slot antenna, and the antenna area was reduced. The fabricated rectangular slit-inserted tapered slot antenna exhibited a bandwidth of 8.45 GHz and improved its bandwidth by approximately 4.72 GHz. Furthermore, the antenna showed a 15.5 % reduction in area. Rectangular Planar Antenna Using U-Slot for Bandwidth ... On the contrary, the major disadvantage of these types of antennas is the lower and narrow bandwidth[1-5]. Combination of the coplanar waveguide feed, antenna geometry, and a variety of slot shapes is a solution to improve and enlarge the antenna operating bandwidth[6-8].
