Abstract

A novel internal antenna for synchronous code division multiple access band wireless phone is presented. Traditional internal antenna is monopole or Planar Inverted‐F Antenna, which have no gain high enough in the limited space in phone. The proposed antenna is composed of two antenna elements with equal magnitude and 180Β° phase difference, to assure voice quality with high gain. The measured maximum gain is 2.69 dBi and maximum efficiency is 70.1% in the frequency band 450–470 MHz. Β© 2007 Wiley Periodicals, Inc. Microwave Opt Technol Lett 49: 2112–2114, 2007; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.22708

Although we do not know the exact particle-size distribution of the fog in the measured link, the upslope fog is similar in formation to the advection fog; the
