Plasma Antenna has potential to Revolutionalize Antenna Technology

RIDGEFIELD, Conn.--(BUSINESS WIRE)--April 14, 2004-- Markland Technologies,
Inc. (OTCBB: MRKL- http://www.marklandtech.com), an integrated homeland
security company, announced today that its gas plasma research team has been
awarded US patent # 6,710,746 for a gas plasma antenna element demonstrating
re-configurable length. A gas-plasma antenna could revolutionize antenna
technology due to its unique benefits over traditional antennas. A plasma
antenna operates with greater stealth, has the ability to dynamically
transmit/receive multiple frequencies, and is extremely portable.

The company intends to direct its research toward applications for Military and
Homeland Security. This includes applications such as secure broadband wireless
communications and stealth radar. The development of this technology has been
funded to date through Small Business Innovative Research grants from the US
Navy and Army.

The US patent awarded to Markland relates to plasma antennas having
re-configurable length, beamwidth, and bandwidth. Traditionally, antennas have
been defined as metallic devices for radiating or receiving radio waves, or as
a conducting wire, which is sized to emit radiation at one or more selected
frequencies. As a result, the paradigm for antenna design has heretofore been
focused on antenna geometry and physical dimensions. Markland's innovative gas
plasma antenna patent portfolio changes the paradigm, as it is now possible to
design antennas which have greater flexibility and security than conventional
antennas.

Markland CEO Robert Tarini stated, "We anticipate that our Gas Plasma Antenna
(GPA) intellectual property portfolio will provide a revolutionary new set of
advanced capabilities to the Department of Defense and Department of Homeland
Security as they endeavor to deal with an ever changing landscape of
challenges. Our plan for the GPA technology is to transition it from its
present stage of development, where we have multiple active government funded
contracts for advanced research programs, to the next stage, where we hope to
be awarded product development contracts to commercialize the technology."
