The new system uses an antenna which is highly directional "Wide Aperture Log Periodic Antenna
Array [LPDA]" system.
NASDAQ: PCTI), a leader in antenna and scanning receiver solutions, announced today the release of the PCTEL Bluewave(TM) high-performance log periodic antenna
with full coverage of the 136-174MHz VHF frequency band for use with wideband radio technology.
Tenders are invited for Supply of broadband log periodic antenna
Using this property, a frequency reconfigurable log periodic antenna

for UHF passive RFID tag design featuring constant power transmission coefficient over broadband operation," Journal of Electromagnetic Waves and Applications, Vol.
The source is a linearly polarized, log periodic antenna
that operates from 500 MHz to 12.
The Model ATR26M6G-1 is a 26-MHz to 6-GHz, 5,000-W wideband, high-gain radiant arrow/log periodic antenna
with the proprietary bent-element design.
The Radiant Arrow 80 [TM] improved log periodic antenna
covers the 80 MHz to 5 CHz frequency band, and offers broader bandwidth with greater power handling and a smaller size than existing log periodics.
This approach, combined with basic log periodic antenna
concepts such as self-complementary structures, led to a dual polarized sinuous aperture concept.
Patent and Trademark Office that the patent for its Microstrip Fed Log Periodic Antenna
application will be granted on April 26, 2005, with Patent No.
Here, the radiation patterns in the xy-, xz-, and zy-planes were measured with a log periodic antenna
as the transmitting antenna and the antenna being measured on a turntable as the receiving antenna.
For example, a conventional log periodic antenna
can easily be designed to provide low SWR over several octaves of frequency.
