چکیده مقاله :
The proposed structure is a closed-loop dual-band filtering antenna, in which the antenna and the resonator are combined together. The filtering antenna consists of two triangular resonators and a rectangular loop micro-strip antenna. The surface structure of a Rogers RO-4003 substrate with dielectric (εr) equal to 3.55 and insulation loss tangent (tgδ) equal to 0.0027 and a thickness of 32 mm is placed at frequencies of 3.4, 5.28 and 8 5.5 GHz, which indicates a return loss below 10 dB. This structure is suitable for Wi-Max and the fifth generation mobile communication network, and the filter antenna proposed for these applications has a suitable bandwidth and radiation pattern in its resonance frequencies. The design and analysis of the structure has been done using HFSS software. To confirm the correctness of the simulation results, a laboratory sample of the proposed filtering antenna is made and it shows the correctness of the measured values of the design and simulation
