TLDR
In this article, a planar dual-band inverted F-antenna for hand held portable telephones has been realized to operate at 0.9 and 1.8 GHz bands.Abstract:
A novel planar dual-band inverted F-antenna for hand held portable telephones has been realised to operate at 0.9 and 1.8 GHz bands. The dual-band antenna is almost the same size as a conventional inverted F-antenna operating at 0.9 GHz, and has an isolation between bands of better than 17 dB.read more
