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 …

Broadband Circularly Polarized Cross Shaped Slot Antenna with ... Broadband Circularly Polarized Cross Shaped Slot Antenna with an Improved Feedline Kwame O. Gyasi, Guangjun Wen, Yongjun Huang, E. Aﬀum, and Wei Hu Abstract—A broadband circularly polarized cross-shaped slot antenna with a parasitic cross-shaped patch and an improved feedline is proposed for wireless applications between 3–6GHz. In order to E SLOTTED RECTANGULAR MICROSTRIP ANTENNA WITH COAXIAL FEED ... FDTD algorithm in MATLAB and compared for a non slotted microstrip patch antenna, a rectangular slotted microstrip patch antenna and an E slotted microstrip patch antenna. From the simulated results, Bandwidth for the rectangular slotted antenna and E slot design is found to be as large as about 2.4 times and 3.149 times

the bandwidth, D, and 77 at these frequencies. The second- resonance frequency is about 2 f, . The efficiency is less than that at f, by about 20%, and the antennas are more directive at fc2 than at f, . In [3], an antenna with a rectangular slot and a rectangular slot loop-fed with a coplanar waveguide were designed to work at

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.

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

A compact monopole antenna with improved bandwidth for Ku… A compact monopole antenna has been presented with improved bandwidth for Ku- band applications. The proposed Ku-band antenna is made of rectangular slots and circular slots on the ground and the patch, respectively, by a microstrip line of 50 Ω. It is designed on a printed circuit...
