✦ Synopsis

In this paper, two types of wideband crossed planar monopole antennas having the band-notched characteristic have been proposed and tested. The simulated and measured results show that a sharp frequency band notch has been created very close to the center frequency of the 3.6-GHz band with a fractional bandwidth of approximately 10% to 15% by inserting the U-shaped slots. The notched frequency can be also changed by adjusting the lengths of the slot (L s1 , L s2 ).

## Abstract A novel composite right/left‐handed transmission line is presented in this letter. The proposed CRLH structure can be considered as a CPW version composed with a pair of parallel spiral interdigital and a conjunctive stub. The spiral interdigital enlarges the series capacitance, and the

## Abstract In this letter, a novel via‐free composite right‐ and left‐handed transmission line (CRLH TL) is proposed using defected ground structure (DGS). The required shunt inductance and series capacitance for left‐handed transmission line are provided by the mender‐line of DGS and inter‐digita
