A design of compact size and multi-band composite right-left handed meta-material antennas for wireless applications is presented. The proposed antenna consists of single left handed cell. The series interdigital capacitor and short circuit stub which acts as shunt inductor are considered the main block of the proposed antenna. The proposed antenna is designed to operate at different frequency bands...
A compact size microstrip fed UWB antenna with dual-band notched characteristics is presented in this paper. The first band notch is achieved by using defected microstrip structure band stop filter which is inserted in the microstrip feed line to reduce the interference with the WLAN from 5.1 GHz to 5.9 GHz. The second notch is accomplished by using a meandered slot etched in the radiating patch to...
This paper presents design of compact tunable dual band asymmetric coplanar strip -fed monopole antenna based on graphene sheet. The proposed antenna is consisted of ACS-fed folded monopole antenna with inverted two L branches which achieve very compact size. The proposed antenna is operated at 2.4 GHz and 5.8 GHz which is used for wireless applications. The graphene sheet is used to achieve the desired...
This paper presents a dual band MIMO metamaterial based antenna. The antenna demonstrates dual input/output, the first one operates at 2.45GHz and the second one operates at 5.8 GHz. The two individual antennas are designed employing only one left handed unit cell. The proposed MIMO antenna has the advantage of compactness (its size is only 2.2 × 4.2 cm2). The design represents size reduction of approximately...
