Introduction (1)
n Wireless Communication devices
n Cellular phones (bar type, folder type)
n Laptops or Tablet PCs
n Personal digital assistants (PDAs)
n WLAN in-building access points (on-ceiling,
on-wall, or-desk)
n Operating bands
n AMPS, GSM, DCS, PCS, UMTS, etc. (850, 900,
1800, 1900, 2050 MHz bands, etc.)
n WLAN band (2.4, 5.2, 5.8 GHz)
n Ultra-wide band (3.1~10.6 GHz)
Some Promising planar antenna types
n Planar inverted-F antennas (PIFAs)
n Very-low-profile monopoles (bent, folded)
n Printed monopole/dipole antennas
n Metal-plate antennas (constructed using
line-cutting or stamping)
n Slot antennas (stamped from metal or
integrated with system ground plane)
n folded dipole antenna
n Ceramic chip antennas (SMT devices) |
