SKIT Research Journal Wi-MAX this antenna is reported in this paper. stands for Worldwide Interoperability for Microwave Access and is proposed under the IEEE standards 802.16d and 802.16e 2. Antenna Design AND Analysis (1-4).
A novel substrate-integrated waveguide (SIW) cavity-backed slot antenna is ... The peak gain is remarkably improved with the use of an SIW cavity and metallic superstrate. The superstrate comprises a single rectangular slot window and two ... include a wide bandwidth, when compared with a microstrip patch antenna, and ...
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 … Patch Antenna with enhanced gain. The aim of the project is to design a rectangular Microstrip Patch Antenna with enhanced gain and bandwidth and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant (ε r), substrate thickness on antenna gain and bandwidth. Radar Basics - Slot Antennas The band width of a narrow rectangular slot is equal to that of the related dipole, and is equal to half the bandwidth of a cylindrical dipole with a diameter equal to the slot width. Figure 2 shows slot antennas different from the rectangular shape that increasing the bandwidth of the slot antenna. ENHANCEMENT OF BANDWIDTH OF RECTANGULAR PATCH …

DESIGN OF OPEN SLOT ANTENNA FOR BANDWIDTH … 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 Slotted rectangular microstrip antenna for bandwidth 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 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.
With the much attention to reduce the slot size in antenna design. use of the offset microstrip feed line and the corner-trun- cated protruded ground plane, the bandwidth enhancement In recent years, some techniques of compact slot and …
