This antenna is an inverted E-like shaped monopole with a T-stub shaped ground plane. Influence of bandwidth on asymmetry of the “E” characteristic is intensively discussed. In the meanwhile, we found that asymmetry may be used to improve our antenna’s bandwidth with a proper substrate thickness. The wide bandwidth, especially at the low frequency range, is also largely dependent on where to place the “T-stub” part of the ground plane.
