Abstract: This article presents, 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. The modelled prototype of filtenna is tested and the results are compared between the simulated and the fabricated filtenna. 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.
