Ceiling-Tile Antennas
Ceiling-Tile Antennas
In some cases, antennas must be totally hidden. This makes for
an extremely tough installation. One possible solution is called a ceiling-tile antenna. Centurion Wireless Technologies
offers such an antenna (see Figure
C-5).
Although the antenna is pleasing aesthetically, it does have
reduced coverage when compared to a typical "below-the-ceiling" antenna. Some of
these ceiling-tile antennas come in multiple frequencies, offering a single
antenna for servicing of paging systems, wireless phones, and wireless LANs, for
example. The gain of ceiling tile antennas is usually fairly low, with 3 dBi
being typical. |
