Improvements in the performance of microstrip antennas on finite ground planes through ground plane edge serrations

Ground plane edge serrations for improved performance of microstrip active reflectarray elements

“…Antenna radiation patterns were taken and match closely with previous studies [5], [6]. It is also evident that the square surface removed from the patch does not significantly alter the radiation characteristics; this result agrees with previously published work [3], [4].…”

“…Previous studies concerning the use of ground plane edge serrations for microstrip patch antennas have demonstrated several improvements in the overall operation of the device. Recent research [5] shows that ground plane serrations produce improvements in the polarization characteristics and radiation beamwidth. These effects were examined in [6] for the case of corner-fed and dual-fed orthogonally polarized patch antennas, with the latter being similar to the operation of the antenna structure utilizing the slot-amplifier reflectarray element design.…”

High Gain Circular Waveguide Array Antenna Using Electromagnetic Band-gap Structure

“…These materials are formed of dielectric structures that are periodic in one or more dimensions [2]. Many novel antennas based on EBG technology have been proved very useful [3,4]. It is noted in [5,6] that high directivity can be obtained from conventional patch antenna using a defect mode of Fabry-Perot type EBG cavities.…”

A sectoral horn antenna based on the electromagnetic band‐gap structures

“…In recent years, the EBG material have been widely researched and applied in the microstrip antennas to suppress the surface wave propagation that improves antenna's performance such as increasing the antenna gain and reducing back radiation [5,6]. Whereas, as the common used components in radar and satellite communications system, the horn antenna with EBG material has been rarely reported on all kinds of literatures [7].…”
