Abstract :
In this paper, a dielectric-loaded broadband antenna with frequency-insensitive E-plane radiation pattern has been designed. The optimized antenna with a dielectric has more constant and higher gain than the antenna without a dielectric and also has low return loss over wideband. Consequently, it is found that loading a dielectric and designing antenna shape is effective to improve E-plane radiation pattern and return loss simultaneously.
