Enhanced Bandwidth of UWB Microstrip - ijert.org Figure 2 shows the antenna with u-slot and finite ground plane. Here patch is 16 mm wide and 12 mm long. Dielectric material is 30 mm wide and 30 mm long and height of the substrate is 1.6 mm. Ground plane is partial providing good impedance match with width 30mm and 8mm length. U-shaped slot is used to decrease the overall antenna Open slot antenna in a small ground plane - IET Journals ... Abstract: The impact of a finite ground plane on an open-slot antenna performance is reviewed and the far-field pattern behaviour is clarified. The pattern of this slot configuration is fundamentally different to its complementary dipole. Design of an efficient miniaturized UHF planar antenna ... antenna operating around 600 MHz is presented to validate the design procedures and simulations. Finally the effect of the finite size ground plane on this type of slot antenna is addressed. II. DESIGN OF A MINIATURIZED UHF ANTENNA Equiangular and Archimedean spiral antennas [7], [8] are commonly used as broadband antennas. These antennas usu-

DESIGN OF A MICROSTRIP-FED MONOPOLE ANTENNA WITH A WIDE ... In this paper, the design of a microstrip-fed monopole antenna with a wide slot ground plane for uwb applications is presented. A wide slot ground plane is inserted in the ground plane and etched. Chapter 5 Impedance of Slot Antennas 5.1 Introduction Figure 5.1) Micostrip-fed slot antenna radiating on a layered substrate. The layers are chosen to enhance the radiation through the dielectric stack. The electrically thin substrate supporting the microstrip line can be easily made by a liquid polymer that can be applied over the ground plane. The slot length is CYLINDRICAL DIELECTRIC RESONATOR ANTENNAS FED BY A STAIR ... CYLINDRICAL DIELECTRIC RESONATOR ANTENNA FED BY A STAIR SLOT IN THE GROUND PLANE OF A MICROSTRIPLINE H. RAGGAD 1, M.

element and cutting slots (or slits) in the ground plane [6]-[9]. In this paper, we present a new multiband PIFA antenna based on combination of a meandered slot in the antenna structure and an additional slot in the ground plane. Introducing slot in the PIFA radiating element and on its
A prototype of the bow-tie slot antenna is fabricated and the return loss is measured using the HP 8510C vector network analyzer (VNA). The fabricated antenna has a finite ground plane truncated at 1 cm away from the bow-tie slot edge. The antenna with the connector is simulated THE EFFECT OF GROUND PLANE ON THE PERFOR- MANCE OF A SQUARE ... In this paper, the ground plane efiect has been studied on a simple square loop CPW-fed printed antenna. The edges of the ground plane where the currents are concentrated have been gradually shaped and the antenna characteristics have been studied. The study has shown that the ground plane is a dominant factor in establishing the antenna’s Electrically-Small Antenna Performance Enhancement for 5.5 Multi-Resonant Patch - U-Slot Antenna 84 5.5.1 Sensitivity to Finite Ground Plane 88 5.5.2 Discussion - U-Slot Microstrip Patch Antenna 89 5.6 Conclusions 89 5.7 References 90 6 CHAPTER - Hardware Technologies.....91 6.1 Introduction 91

US7075493B2 - Slot antenna - Google Patents The reduction in the directivity of the slot antenna with a finite ground plane can also be attributed to the radiation from the edges and surface wave diffraction. To further study the effect of the size of the ground plane, the same antenna with a slightly larger ground plane (0.58 λ 0 ×0.43 λ 0) was fabricated and measured. Table 6 shows ...

UWB Slot Antenna on a Folded Finite Ground Plane - infona.pl An innovative antenna based on a printed rectangular slot etched in a finite ground plane which is folded conformably to a boxed structure is proposed for UWB applications. The antenna is fed by a 50Omega microstrip line printed in a dielectric substrate. Due to geometry, the finite folded ground allows the far-field radiation patterns to fill the entire space. An antenna prototype has been designed, built and tested, showing an input impedance bandwidth which covers the entire UWB FCC ... Investigation of wide-band microstrip slot antenna - IEEE Journals ... Abstract: This paper presents the simulation and experimental investigations of a printed microstrip slot antenna. It is a quarter wavelength monopole slot cut in the finite ground plane edge, and fed electromagnetically by a microstrip transmission line.
2008-10-31 · I am simulating a dielectric resonator antenna fed by a slot in the ground plane. Underneath the ground plane is the inverted microstrip line to couple the power from the stripline to the antenna via the slot. I am trying to simulation it using the infinite ground plane. In HFSS 10, this is easily done by just checking the "infinite ground plane" box when we assign PEC boundary condition to Pattern Synthesis of a Waveguide Slot Array Antenna for …
