A half-U-slot-cut and rectangular-slot-cut are used in rectangular microstrip antenna to increase gain and bandwidth of antenna[6].The reverse L-shaped slot is connected from bottom of rectangular Wideband rectangular slot antenna for personal wireless 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 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. ENHANCEMENT OF BANDWIDTH AND GAIN OF A …
the rectangular stub of the open slot antenna are shown in Figure 3. From the simulated and measured results, it is obvious that the rectangular stub can improve the bandwidth performance of the open slot antenna. The bandwidth of the open slot antenna with the rectangular stub is approximately 139% from 2.57 to 14.23GHz, while

IMPROVED DUAL BAND-NOTCHED UWB SLOT AN- TENNA WITH ... 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 Implementation of rectangular slit-inserted ultra-wideband ... In this paper, a tapered slot antenna capable of ultra‑wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit‑inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon Comparative Analysis and Bandwidth Enhancement with ...
