Microstrip Patch Antenna Array on Ground with Circular Pbg
In this paper, a microstrip patch antenna array on ground with PBG is simulated and measured. It is shown that the photonic band-gap (PBG) can suppress harmonics and optimize the current distribution on the patches. As a result, the gain of the antenna array is improved and the side-lobe level is reduced. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 41: 127–130, 2004; Published onl...
متن کاملA compact planar inverted-F antenna with a PBG-type ground plane for mobile communications
The ground plane affects the characteristics of a planar inverted-F antenna (PIFA) significantly. Using the idea of the high-impedance surface to construct the ground plane, a new type of compact PIFA with a photonic bandgap type (PBG-type) ground plane is proposed. Both the traditional PIFA and the proposed antenna are analyzed using the finite-difference time-domain (FDTD) method in detail. I...

متن کاملEffects of Substrate Permittivity on Planar Inverted-F Antenna Performances
This paper quantifies the gain and matching bandwidth variations of a planar inverted-F antenna (PIFA) for several dielectric substrates. The performance of the PIFA is assessed in two configurations. First, the PIFA is studied with different substrates for a radiating patch of fixed dimensions of 4.92 cm x 2.13 cm. The effects of the dielectric constant of the perfect and lossy substrates on t...
متن کاملTuning Microstrip Patch Antennas on Ferrite Substrate Using Simple Ground Plane Structures
An additional tuning strategy for microstrip patch antennas on magnetized ferrite substrates is presented. It is shown that by introducing simple ground plane structures, the response of the patch antenna can be improved considerably. The analysis method is based on a 3D FDTD algorithm. The FDTD model utilizes the auxiliary differential equation approach to represent the frequency dependent per...
