| Abstract | ||
| This article proposes a new design structure of a wideband Microstrip filtering antenna. The design structure of Microstrip filtering antenna is based on the integration of Parallel Coupled Microstrip Line Stepped Impedance Resonator (PCML - SIR) filter with the Monopole patch antenna. The proposed filtering antenna is suitable for high-speed data rate transmission applications, which has a center frequency . The planned structure has a Fractional Bandwidth (FBW) of about 20 %, a return loss ( and a gain over the passband frequency equals to ( 2.88 dB). The proposed microstrip filtering antenna has a good radiation efficiency of about (71.67 %). This design has an incomplete ground plane and a reversed L-shaped slit loaded. The proposed filtering antenna design was simulated using Computer Simulation Technology (CST) Studio Suite software. The design shows a good agreement matching between the PCML-SIR filter and the monopole patch antenna. The simulation design results showed a low loss in the passband and high suppression of the spurious responses in the stopband. The main goal of the PCML-SIR design is to use for high-speed data transmission, which needs to spread frequency spectrum. | ||
