In this paper, we propose an FSS based on a double split ring resonator (DSRR). The DSRR FSS has better skirt characteristic than the conventional strip FSS. By appropriately adjusting the gap and line width, the resonant frequency and skirt characteristic can be adjusted. To validate the FSS characteristics, an L probe patch antenna for CDMA was designed. The gains with and without FSS were compared...
A compact multiband antenna using a double-negative (DNG) zeroth-order resonator (ZOR) for global system for mobile communications (GSM850/1800/1900, 824894/17101880/18501990 MHz), wideband code division multiple access (WCDMA, 19202170 MHz), and wireless broadband (WiBro, 2.32.4 GHz) operations is presented. The proposed antenna having a total volume of 40 times 6 times 3 mm3 comprises a lower-band...
