Design of cavity-backed slot antennas using the finite ... Design of Cavity-Backed Slot Antennas Using the Finite-Difference Time-Domain Technique Manabu Omiya, Member, IEEE, Takashi Hikage, Student Member, IEEE, Norio Ohno, Kenich Horiguchi, and Kiyohiko Itoh, Senior Member, IEEE Abstract— A cavity-backed slot antenna is thought to be one of the most suitable elements for the wireless transmission of Cavity-Backed Slot/Strip Loop Antenna — Remcom ... In this example a cavity-backed slot/strip antenna is simulated in XFdtd using the XACT meshing feature. The simulated results for return loss, axial ratio, and gain are compared to measured results. The antenna design and measured results are taken from [1]. A CAD representation of the antenna structure is shown in Figure 1. Cavity backed dual slot antenna for gain improvement - Li ... A simple method of gain improvement for the cavity backed slot antenna based on the substrate integrated waveguide technique has been presented in this article. By using dual slot at the cavity edges to substitute a single slot at the cavity center as the radiating element, gain of the cavity backed slot antenna has been improved about 1.7 dB ...
Microstrip-fed cavity-backed slot antennas | Zhongxiang ... Detailed study of cavity-backed slot This article presents two types of cavity-backed slot antennas (CBS) antennas can be traced back three or four decades [5– 8]. A fed by a microstrip line and operating at 5.8 GHz: One is a linearly variational expression of the admittance of a rectangular CBS was obtained by Galejs [5], where the slot was excited by a current source across its center. A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. DESIGN OF A HIGH-GAIN CAVITY-BACKED SLOT ANTENNA WITH ... Antennas like horn, Yagi- Uda and cavity backed slot can produce high gain. The horn is usually bulky, therefore an integrated horn antenna with fairly low proflle at 60GHz was presented in [8] that produces 14.4dB gain. However, the antenna size is still large (5:2‚ £ 4‚). cavity-backed slot antenna (CBSA) - University of Nairobi ...
