Substrate Integrated Waveguide Fed Dielectric Rod Filtenna

In this paper, a dielectric rod fitenna is proposed in x-band. To get the filtering characteristics, a Substrate Integrated Waveguide (SIW) based band pass filter is used to feed the dielectric rod through a slot. The proposed structure is exhibiting a band width of 4% at 10 GHz. The peak gain is 9 dBi in the operating band for a
$1\lambda 0$
long dielectric rod radiator. The gain of the proposed antenna can be increased using longer length of radiator.
