## Abstract A microstrip antenna array with a low sidelobe level and circular polarization for the 2.45 GHz RFID reader application is introduced. The measured results show that the array achieves a sidelobe level of โ26 dB, the axial ratio of under 3 dB within main lobe, a VSWR โค2 impedance bandwi

Agreement between two-port results and circuit simulator results is excellent. The difficulty of slotted line measurements is visible in the rough curvature o
## Abstract Based on the conventional microstrip antenna, a broadband circularly polarized microstrip antenna fed by electromagnetism coupling is designed, which is composed of three substrates. The frequency band is broadened not only, but also the circular polarization axial ratio is effectively
## Abstract A compact design of a single feed microstrip antenna for circular polarization (CP) is proposed and studied.CP is brought about by embedding a slot in a cross shaped patch. The structure enables an area reduction of 46% as compared to conventional rectangular microstrip antenna. The ant
