A MICROSTRIP SMALL-SIZED ARRAY ANTENNA BASED ON THE META-MATERIAL ZEROTH-ORDER RESONATOR

Zeroth Order Resonator Antenna (ZORA) using CRLH Transmission Lines

A compact Zeroth Order Resonator Antenna (ZORA) is implemented as a part of course work for Radio Frequency Integrated Circuits and Systems (E8-242). This work is based on [1] . Due to the unique properties of Compact Right/Left Handed (CRLH) transmission lines, the size of the antenna is independent of the frequency of operation. This compact structure is made of two unit cells each comprising...

Analysis of Metamaterial Based Microstrip Array Antenna

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Cpw-fed Zeroth-order Resonator Antenna Using Shorted Crlh Transmission Line

A novel composite right/left-handed (CRLH) coplanar waveguide (CPW)-fed zeroth-order resonator antenna is proposed. The shorted CRLH transmission line exhibits zeroth-order resonance at 2 GHz and operates with narrow bandwidth. The dispersion analysis is also carried out and presented in this article. The proposed antenna has been fabricated and tested. Omnidirectional radiation pattern with a ...

Dual Linearly Polarized Microstrip Array Antenna

Recently, Multiple Input Multiple Output (MIMO) has become popular research topic among researchers for development of a new wireless communications technology. The system capacity can be increase with deployment of MIMO technique in the communications system. Thus, the used of high frequency bandwidth can be avoid since this method required high cost implementation. High transmitted power also...
