Metamaterial-based electronically controlled transmission-line structure as a novel leaky-wave antenna with tunable radiation angle and beamwidth (2004, methodology): “For an LW antenna application [15], the radiation angle is determined by the following simplified relationship in the dominant mode”
Leaky-Wave Antennas (2008, methodology): “3) Quarter-Wave Transformer LWA: After the CRLH structure was conceived [18], it was realized that Bconventional[ periodic LWAs that radiate from the n 1⁄4 1 space harmonic could also be constructed that can scan through broadside.”
A compact enhanced-bandwidth hybrid ring using an artificial lumped-element left-handed transmission-line section (2004, background): “Recently, a transmission-line (TL) approach of LH materials [4], [5] and practical implementations of them were proposed in different applications [6], [7].”
Transmission line approach of left-handed (LH) materials and microstrip implementation of an artificial LH transmission line (2004, background): “The unique properties of LH metamaterials, verified by full-wave analysis in [14]–[16], are promising for a diversity of optical/microwave applications, such as new types of beam steerers, modulators, band-pass filters, superlenses [17], microwave components [13], [18]–[21] and antennas [22], [ 23 ]”
A novel mixed conventional microstrip and composite right/left-handed backward-wave directional coupler with broadband and tight coupling characteristics (2004, background): “Several novel concepts and applications for microwave components and antennas have already emerged from the transmission line approach of metamaterials [4], [6]–[9].”
Transmission Line Modeling and Asymptotic Formulas for Periodic Leaky-Wave Antennas Scanning Through Broadside (2011, background): “While the first planar periodic leaky-wave antennas were reported back in the 1980s, they experience a regain of interest nowadays following recent contributions on novel broadside optimum designs [3]–[5] and on designs with novel features or system functionalities [6]–[12].”
Transversal Asymmetry in Periodic Leaky-Wave Antennas for Bloch Impedance and Radiation Efficiency Equalization Through Broadside (2014, background): “Systematic closure of the open-stopband by means of balancing series and shunt resonances, , was first reported in the context of symmetric CRLH P-LWAs [6], [10].”
Full-Wave Modal Dispersion Analysis and Broadside Optimization for a Class of Microstrip CRLH Leaky-Wave Antennas (2008, methodology): “As mentioned before, a metamaterial leaky-wave antenna has been proposed in which the open stopband can be suppressed and broadside scanning can be achieved [2], [4].”
Electronically scanned composite right/left handed microstrip leaky-wave antenna (2004, background): “Based on this concept, a backfire-to-endfire LW antenna operating in the dominant mode was developed and shown to exhibit backfire to endfire radiation capabilities in the dominant mode [7], while conventional LW antennas operate in a higher mode and cannot efficiently radiate at broadside.”
A Novel Technique for Open-Stopband Suppression in 1-D Periodic Printed Leaky-Wave Antennas (2009, background): “, the microstrip Composite Right/ Left-Handed (CRLH) LWA, has been proposed that does not suffer from this problem [14], [15].”
Planar Leaky-Wave Antenna With Flexible Control of the Complex Propagation Constant (2012, background): “These CRLH-MLWAs are based on much more complicated periodic unit-cells to make the dominant microstrip mode become leaky, providing full scanning capability, including radiation at broadside.”

High-gain active composite right/left-handed leaky-wave antenna (2006, background): “So far, the emphasis in CRLH LWAs has been on the scanning capability and little work has been published on the aspects of gain and active CRLH LWAs.”
