INTRODUCTION Communication can be broadly defined as the transfer of information from one point to another [1]. Communication between human beings was first done through voice. With the desire to increase the distance of Gain Enhancement of a Wide Slot Antenna Using a Second-Order ... Gain enhancement of a wide slot antenna over a wide frequency band using a low profile, second order bandpass frequency selective surface (FSS) as a super-strate is presented in this paper. The proposed multilayered FSS with non-resonant unit cells in each layer allows in-phase transmission of waves radiated from the antenna BANDWIDTH AND GAIN ENHANCEMENT OF A SLOTTED BOWTIE ANTENNA ... was applied on slotted bowa -tie microstrip antenna. The antenna was designed and simulated using HFSS software. The results obtained showed that by suppressing surface waves and reducing dielectric loss, the gain of the signed antenna de has been enhancedby more than 2 dB withan increase of up to 1.5GHz in the bandwidthThis. new design is Enhanced-Gain Planar Substrate-Integrated Waveguide Cavity ... High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems. A number of enhancement techniques for antenna gain have been studied –. To realize enhanced-gain performance, a cavity-backed slot antenna (CBSA) is employed in this study because of its unidirectional characteristic.

Chapter 8 Slot Antennas - eetrend.com SLOT ANTENNAS Tapered slot antennas (TSAs) were first introduced in the late 1950s. It was then that Eberle et al9 produced a waveguide-fed, flared slot antenna for use in aircraft skins where conventional antennas could not be easily integrated. Gibson10 then developed the strip-line-fed, exponentially tapered slot antenna, which he called the ...
