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
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 Rectangular Planar Antenna Using U-Slot for Bandwidth Improvement In this study, we have performed the conception and the achievement of a new low cost rectangular planar antenna by using slot technique for bandwidth improvement. After many optimizations of the antenna structure, we have validated the antenna structure with a bandwidth of 500MHz. 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 ...
