I am using the following antenna to form an
array that can radiate two different patterns
with appropriate switching.
First mode is called anti-jam mode and we
request highest directivity as possible. I am ok
Second mode is normal mode and
we want a radiation similar to stand-alone
antenna, Which is 5 dB peak gain and 90-100
degree HPBW. Despite all my trials I havent been
able to achieve this mode. When I activate one
element of the array, gain reduces significantly
due to mutual coupling, when I activate two
elements, hpbw decreases. Increasing element
spacing reduces coupling however axial ratio
deteriorates this time. How I can I achieve
those two beamform properly?
I am using
FEKO and can upload feko files upon request.
