This paper presents a triband antenna with simple design for X-band applications. The proposed is designed based on patch truncated corner slot and complementary split-ring resonators in the ground plane. In this way, exhibits three operating bands its resonant frequencies can be controlled independently by changing dimensions of resonator structures addition, due to antiresonant behavior struc...

In this article, the approach involving Dynamic Threshold Optimization (DTO) algorithm is considered to optimize a new compact reconfigurable antenna to be applied to triple band Radio Frequency Identification (RFID) and to ultra wideband (UWB) antenna with multiple bands notched. The antenna is implemented by using the existing techniques, such as loading an L-type band-stop filter, inserting ...

This paper proposes new design of Ultra-Wideband (UWB) antennas using multiple rings with and without notch. A parametric study of antenna parameters, including the length and width of the ground plane, the gap between the patch and ground, and iteration number is presented. The optimized design has been printed on a FR4 substrate of εr = 4.3, h = 1.53mm with substrate size of 44.2mm x 45 mm. T...
