A Diminutive Multi-Octave Super Wideband Printed LPDA Antenna For EW Applications

A diminutive multi-octave super wideband Printed Log Periodic Dipole Array (PLPDA) antenna is presented in this communication. Its operational frequency band is 1.5 to
$33GHz$
. The introduced design has a super wide impedance bandwidth (182.61%) with a maximum realized gain of
$9dB$
and over the band VSWR
$< 2$
. It has a compact size and simple classical structure thus having ease of fabrication. The accomplishment of the propounded antenna makes it competent for electronic warfare (EW) systems as it is befitting for
$L$
, S, C, X, Ku, and Ka band applications. The antenna modeling and simulations are performed by using ANSYS HFSS (High-Frequency Structure Simulator).
