Abstract :
A wideband epsilon negative (ENG) zeroth-order resonant antenna designed on a microstrip line is presented. It has a mushroom structure and its size is only 0.040??0 ?? 0.235??0 ?? 0.073??0 at 9.2 GHz owing to zeroth-order resonance. The design procedures with closed-form solutions are provided using transmission line theory. The measured (simulated) antenna bandwidth is about 20.0 (13.0%) and antenna gain is 7.1 dBi (7.2 dBi), at 9.2 GHz, despite the compact size.
