Matching Slot Role in Bandwidth Enhancement of SIW Cavity ... cavity and a rectangular slot close to the feed point has been etched (to add extra resonance to enhance the bandwidth of the antenna in the desired frequency range). Tuning the rectangular slot improved the fractional bandwidth to 8%. A 7.9 dBi peak gain and a steady beam over the entire bandwidth are achieved. What is the difference between slot antenna and patch antenna ... Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas Design of a Corner Cut Rectangular Microstrip Antenna Having ...

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 ...

A single layer single element rectangular microstrip antenna on ridge ground plane for improved bandwidth is theoretically investigated with a view to develop a concrete physical insight in to the phenomenon. The simple single element probe fed rectangular microstrip antenna fabricated on conventional PTFE (Poly Tetra Fluride Ethelene) substrate have many advantages except its narrow bandwidth. Wideband rectangular slot antenna for personal wireless ...
A rectangular slot antenna with improved bandwidth ... 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.
