Abstract

Wireless energy harvesting of incident waves for electronic devices through rectenna investigated in recent years has proved to be efficient. In work published till date antennas used in rectenna are of limited bandwidth or bulky. This paper presents an E-patch antenna with improved bandwidth and efficiency. Techniques to make trade-offs required for widening the frequency band without variation in efficiency are introduced. The E-patch is electro-magnetically coupled with similar patches and the feeding point location is decided for further increase in bandwidth. An increase of 33% in bandwidth is noticeable with an advantage of multiband operation. The Epatch is investigated for WLAN frequency bands and the coupled patch is investigated for ISM as well as WLAN frequencies.
