Abstract :
A novel design of the inset-microstripline-fed circularly-polarized microstrip antenna by using a corner-truncated patch with an inserted slit is first successfully implemented. By further inserting slits at the corner-truncated patch boundary, the compact inset-microstripline-fed circularly-polarized microstrip antenna is also studied. Results have been obtained that, due to the inset-microstripline-fed reactive effect, this truncated corner perturbation can not be directly applied to the inset-microstripline fed circularly polarized microstrip antenna with good impedance matching condition.
