Design of compact planar antennas using LH-transmission lines

Metamaterial-Based Compact Filter Design

“…In other words, rather than embedding the electrically small resonant metallic inclusions into the host material, the left handed feature can also be realized with low loss by periodic loading of conventional microstrip transmission lines with series capacitors and shunt inductors in planar microwave technology [Caloz & Itoh, 2005;Eleftheriades & Balmain, 2005]. Many microwave circuits have been implemented by using this strategy such as compact broadband couplers [Nguyen & Caloz 2007], broadband phase shifters [Eleftheriades & Balmain, 2005], compact wideband filters [Gil et al, 2007], compact resonant antennas [Lee et al, 2005[Lee et al, , 2006Schüßler et al, 2004;Sanada et al 2004].…”

A Compact Dual-Mode Metamaterial-Inspired Antenna Using Rectangular Type CSRR

“…Metamaterial-antennas are a class of antennas which use the properties of metamaterial to enhance the performance and miniaturize the antenna systems. A lot of research work on compact resonant antennas is reported based on CRLH TL's in [5][6][7][8], but those antennas have the problem of narrow bandwidth. Recently, some new types of approaches are outlined in order to enhance the bandwidth of the metamaterial antennas.…”

Analytical Modeling of the Printed Dipole Antenna Loaded With CRLH Structures

“…In [6] a leaky wave antenna consisting of microstrip transmission lines has been presented. The left-handed TL concept has been also applied to small antennas constructed on a ground plane [7,8]. Applications such as an infinitesimal dipole immersed in left-handed material [9], the left-handed ladder network to form a small dipole antenna [10], a short dipole antenna and an orthogonally polarized dipole antenna have been studied in [11].…”
