Microstrip patch antenna with defected ground structure #x00026; defected microstrip structure

摘要

In this paper we propose the antenna geometry to design a very compact microstrip patch antenna using thin dielectric substrate having low dielectric constant. This antenna provide better efficiency, better band-width without any enhancement in the weight, volume or cost. HFSS [10] high frequency simulator is employed to analyze the proposed antenna and simulated results on return loss, the E-and H-plane radiation pattern is presented. The antenna parameter in frequency domain analysis has been investigated to show its capability as an effective radiating element. Due to low-profile structure it used in the wireless application.
