The successful deployment of wireless systems requires the integration of small, cost-effective antennas while preserving a reasonable electrical performance in the required bandwidth. This paper begins with a short overview of the most important antenna characteristics, and then uses these to describe the minimum requirements and fundamental performance-size limits for electrically small integrated antennas. The performance-size tradeoff is further illustrated by the design of a planar integrated antenna for WLAN. Codesign guidelines are given to avoid parasitic coupling between the integrated antenna and RF circuits. A concluding comparison is made between on-chip and on-package integration of a small antenna for microwave and millimeter wave systems.  相似文献

Bow-tie slot antenna fed by CPW   总被引:4,自引:0,他引:4  
A bow-tie slot antenna fed by CPW is introduced. It is designed to work in the Ku-band around 15.5 GHz. The proposed antenna is analysed both theoretically and experimentally. The presented results include the return loss and the radiation patterns. Two different geometries of the bow-tie antenna are presented and compared. The proposed antenna has several advantages such as a very large bandwidth, good control of its input impedance, and ease of fabrication. The proposed antenna has a dipole like radiation pattern which makes it suitable for mobile communication systems designed to work in the Ku-band  相似文献
