Gain Enhancement of 60-GHz Antipodal Tapered Slot Antenna ... Abstract: A zero-index metamaterial (ZIM) structure is proposed for the gain enhancement of an antipodal tapered slot antenna (ATSA) at 60-GHz bands. The single ATSA loaded with the proposed ZIM cells exhibits a gain enhancement of up to 2.6 dB in the frequency band of 57-66 GHz. (PDF) Gain Enhancement of a Slot Antenna using Multiple ... PDF | We present in this paper a design of a high gain antenna for radar-based non-contact measurement systems in the k-band frequency. The proposed antenna consists of a slot on a multi-grooved ...

F. Gain and Bandwidth Enhancement in Compact Microstrip Antenna In this paper [5], a new compact microstrip patch antenna has been proposed in stacked configuration. The characteristics of the antenna are obtained in terms of return loss, gain and bandwidth and are compared with theconventional microstrip patch. It is observed

BANDWIDTH AND GAIN ENHANCEMENT OF A SLOTTED BOWTIE ANTENNA ... dielectric losses and improving the gain of the antenna, the gain of the patch antenna can be further enhanced by suppressing surface waves [5]. In this research, the effects of partial substrate removal on the performance of slotted bow-tie microstrip antenna were investigated for antenna gain enhancements. The basic idea 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. Gain-enhanced SIW cavity-backed slot antenna by using TE410 ... A gain-enhanced low profile substrate integrated waveguide (SIW) cavity-backed slot antenna is presented in this paper. By etching three parallel transverse slots on the center and both edges of the rectangular SIW cavity as the radiating elements, higher resonance mode of TE 410 can be excited to achieve gain enhancement.

Abstract: The gain enhancement of an annular slot antenna fed by a cavity is studied numerically. The method of moments for bodies of revolution is used as a numerical tool for the simulations. The effect of different parameters is investigated and methods for gain enhancement are proposed.
