Abstract: Current article, a microstrip filtenna with DGS (Defected Ground Structure) is used to implement a LP (Low Pass) filter is designed using a substrate of FR-4 epoxy as the dielectric material. This filtenna consists of a double N-shaped DGS as well as a double closed X-shaped DGS, to improve the performance in terms of wider operational bands, good selectivity and cut-off frequency. The 3dB cut-off frequency of this filtenna is at 2.3672 GHz. To validate the simulated results, are compared with fabricated and measured results. The proposed filtenna has better gain result compared to a conventional antenna in terms of showing better rejection and out-of-band gain which subsequently reduces the interference with the adjacent frequency bands.
