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 IMPROVED DUAL BAND-NOTCHED UWB SLOT AN- TENNA … rejected bandwidth have been presented. A compact slot UWB antenna with two improved notched bands is proposed. The dual band-notched operation is achieved by embedding two sets of composited band-rejected structures on the rectangular slot with chamfered corners or the T-shaped stub. The desired frequency 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. A rectangular slot antenna with improved bandwidth
bandwidth 3GHz=34.1%. The bandwidth is improved up to 37% compared with rectangular patch antenna. Fig. 6 shows the S 11 parameter. Fig. 6. S 11 parameter of Meta-material embedded rectangular patch antenna From the radiation pattern given in Fig. 7, meta-material embedded rectangular patch antenna gives an improved gain of 2.53dB.
