OMNI DIRECTIONAL PLANAR MICROSTRIP ANTENNA
CPW-FED MULTI-BAND OMNI-DIRECTIONAL PLANAR MICROSTRIP ANTENNA USING COMPOSITE METAMATERIAL RESONATORS FOR WIRELESS COMMUNICATIONS A novel approach for the design of a compact multiband planar microstrip antenna is presented.This type of antenna is composed of composite metamaterial resonators (including conditional microstrip resonators and metamaterial resonators), and fed by signal feed.A sample antenna with composite closed-ring resonator […]
COMPACT ULTRA WIDEBAND MICROSTRIP ANTENNA WITH MULTIPLE NOTCHES
In this paper, a new compact circular monopole ultrawideband antenna with multiple narrow bands notched is proposed, which is implemented by using the existing techniques, such as loading a L-type band-stop filter, inserting a split ring resonator (SRR), and the method we proposed that connecting L branches on the radiation disk. Four sharp notches at […]
WIDEBAND STAR SHAPED MICROSTRIP PATCH ANTENNA
A new wideband and small size star shaped patch antenna fed capacitively by a small diamond shape patch is proposed.To enhance the impedance bandwidth, posts are incorporated under the patch antenna.HFSS high frequency simulator is employed to analyze the proposed antenna and simulated results on the return loss, the Eand H-plane radiation patterns and Gain […]
