A compact dual-band bandstop filter (BSF) based on composite right/left handed transmission line (CRLH TL)is proposed and designed without any external impedance matching block. The filter is to suppress the interference of the signal at 5.2 and 5.8 GHz, which is the Unlicensed National Information Infrastructure, radio following the IEEE 802.11a standard and system. The filter is realized by using...
Composite Right/Left handed Transmission Lines (CRLH TL) generally exhibit as metamaterials based transmission line which is composed of periodic repetition of unit cell comprising of a series capacitance and shunt inductance. Metamaterials generally have a wide range of applications. The paper aims at developing a CRLH TL two unit cell structure to work as dual band filter. To get a better understanding...
A novel compact leaky wave antenna based on Composite Right/Left Handed Transmission Line (CRLH) has been proposed and realized on the coplanar waveguide. The equivalent circuit of the proposed structure has been analyzed. The structure radiates at a high frequency of around 18–19GHz. The return loss and the insertion loss have been characterized. The 10dB return loss bandwidth is found to be 4.7GHz...
