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.

Dielectric used in simulations was air. From the analysis, we can observed that the biggest

due to slots in patch and ground plane to design the compact antenna with improved bandwidth and efficiency. II. DESIGN OF RECTANGULAR MICROSTRIP.

Very Small Dual Band-Notched Rectangular Slot Antenna With ... This antenna consists of a rectangular slot, a beveled rectangular patch, two S-shaped slits cut in the ground plane and an elliptical ring slot (ERS) etched in the patch. The corners of a simple rectangular patch are beveled to improve the impedance bandwidth, especially at the middle frequencies of the band.

Bandwidth Enhancement of Compact Circular Slot Antenna for UWB Applications Sonalika P. Kulkarni α& Veeresh G. Kasabegoudarσ Abstract- In this paper the compact circular slot antenna suitable for UWB applications is presented. The bandwidth enhancement technique introduced in this design is using Microstrip X-band Antenna with Improvement in Performance ... : Microstrip X-band Antenna with Improvement in Performance Using DGS . introducing four rectangular slots on patch and for improving performance we etched one rectangular shape slot in ground plane by this slot in ground bandwidth, gain and directivity of proposed antenna are improved. In this Investigation of Microstrip Line and CPW Fed Asymmetrical T ... The overall dimension of the antenna is 90mm x 90mm. The open slot antenna is fed by a 50- microstrip line of width 3.08mm and length 52mm. A dielectric substrate of r =4.4 and height h=1.6mm is used. To obtain improved bandwidth four rectangular slots in T-shape with one inverted are cut in the ground plane. Volume 5, Issue 1, July 2015 Performance Evaluation of an ...

Design of broadband circular patch microstrip antenna with ... a circular patch antenna having U-slot 6. A semi-circular slot antenna with a protruded small rectangular slot was excited by a 50 ohm microstrip line 7 to achieve broadband performance. Krishna et al. 8 reported the improved bandwidth design of a compact dual band slot loaded circular microstrip antenna with a superstrate. 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. 微带天线西文期刊论文 - 天线设计 11.Improved U-shaped stub rectangular slot antenna with tuning pad for UWB applications 12.LEAF-SHAPED MONOPOLE ANTENNA WITH EXTREMELY WIDE ...
