Multi-notched CPW-fed antenna by CSRRs and MLs

Two CPW fed band-notched antenna are presented. In the first antenna by using four CSRRs(Complementary Split Ring Resonators) and a MLs(Meander Lines) on the patch and the feed line, band notched features are obtained in 5.4 GHz-6.5 GHz for WLAN, 7.2 GHz-8 GHz for partial C-band and 8.5 GHz-10.4 GHz for X-band. The presented antenna consists of a square patch which has four CSRRs in four different sides and a feeding line with a ML. The ground of the second proposed antenna includes six MLs which lead to different and multiple band notched. Total size of each antenna is 50×50 mm
