and band-notched designs," IEEE Trans.
An investigation of the impact of finite ground planes on aperture antenna
performance will aid in understanding when the antenna is placed in more complex structures.
Meanwhile, this concept is employed to design reconfigurable aperture antenna
and unit cell of fractal structure as a frequency selective surface [7, 8].

," IEEE AP-S Int.
The coplanar waveguide (CPW) fed aperture antenna
consists of an aperture that is etched from a ground plane having a bow-tie shape and a CPW feed line that protrudes through the aperture.
In 1983, Randtron Antenna Systems (now a division of L3 Communications in Menlo Park, CA) developed a common aperture antenna
with performance equal to or better than a spiral antenna of the same size and capable of simultaneously receiving both senses of circular polarization.
Tornatta said, "Implementing digital variable capacitors in aperture antenna
tuning is quickly becoming an essential tool in the wireless designer's toolbox.
Its basic idea is to use a thin array composed of small aperture antennas
to achieve a large aperture antenna
by performing correlation operations in pairs.
A total of eight layers--three metal, three metallized dielectric substrates and two foam layers--constitute the overall geometry of the stripline-fed, printed aperture antenna
In combining our technical expertise, we are in an excellent position to provide a specific solution to the Satellite Communications community with the introduction of this tactical lightweight transit cased medium aperture antenna
