A rectangular metal Patch Antenna with width W and length L is separated by a dielectric material from a ground-plane by a distance h.The slots or apertures in annular and slotted planar antennas are often employed to improve the impedance bandwidth by changing the current distributions on... Slot Antenna - an overview | ScienceDirect Topics 34, a rectangular slot antenna in an infinite metallic plane is shown with the complementary strip dipole.The design flow to obtain such a topology starts from a rectangular SIW cavity-backed slot antenna with eyelets on the perimeter, which is first reduced by the half through a virtual magnetic... A Wideband Antenna with Circular and Rectangular Shaped … A wideband slot antenna for mobile phone applications is proposed. The antenna has two slots with open ends etched on the opposite edges of the ground plane.Another slot, having a rectangular shape with width of 2.8 mm and length of 26 mm, is employed to enhance the antenna bandwidth. Investigation and Design of a Slotted Slotted waveguide antennas are a class of antenna commonly used in mi-crowave radar applications.There are two suspected causes for the sidelobes. The rst is that the offset of the rectangular aper-tures of the antenna in Fig. 1.2 causes the linear array approximation to become...
In this paper the rectangular patch Antenna with (50) ohm coaxial feed has been designed. The impedance bandwidth of the designed antenna is 177.2 MHZ (7.31% fractional bandwidth). Whereas the impedance bandwidth of the antenna with single trapezoidal slot is 287.2 MHZ (11.93 % fractional bandwidth). That means, the bandwidth

High gain waveguide slot array antenna for 60 One way to improve the bandwidth is to use slots with geometries that can provide larger bandwidth such as wide rectangular slots or so-called dumbbellAn antenna bandwidth of 9GHz centered on 61.5GHz would however cover the entire band in any country (countries that allows unlicensed...
In this paper, conventional inset-fed rectangular patch antenna was designed, simulated, analyzed and modified in other to improve on its bandwidth. Patch antennas inherently have narrow bandwidth, which makes them have restricted areas of application. In other to enhance this narrow bandwidth, this paper combines the use of both the partial ground method and edge-cut techniques of bandwidth
Rectangular Microstrip Patch Antenna With FSS And … Patch antenna has a narrow bandwidth so it has a complexity in tunings so there is a requirement to increase the bandwidth of patch antenna.This antenna is mounted on rectangular patch with air gap to enhance bandwidth for WLAN applications.
Fig -10: Return loss output of SIW Slot Antenna without slit From the simulated and measured results, it is observed that the slit and air gap has improved the bandwidth performance of the slot antenna. The bandwidth of the slot antenna with the slit is approximately 16.15% from 5.33 Bandwidth Enhancement of Coaxial Feed U Slotted Microstrip ... bandwidth in the state-of-the art antenna research. A novel single layer wide-band U slotted rectangular patch antenna with improved bandwidth has been demonstrated. By using a U-slot patch and coaxial feed, a wideband patch antenna which is small in size have been reported. II. FDTD ANALYSIS Fig. 1. The 3-D FDTD unit cell. The FDTD algorithm ... Novel Microstrip Antenna Aims at UWB Applications ... By adding an etched rectangular slot in the ground plane, the antenna gains improved impedance matching and radiation characteristics. An edge-cut technique was employed to reduce antenna size and enhance bandwidth, making this an attractive design candidate for many wideband wireless-communications applications. Multiband Wireless Microstrip Antenna with Embedded Meta ... bandwidth 3GHz=34.1%. The bandwidth is improved up to 37% compared with rectangular patch antenna. Fig. 6 shows the S 11 parameter.
