Metamaterials (MTMs) are artificial electromagnetic materials with novel effective medium properties that may not be available in nature. The concept of metamaterial structures has led to the design of many novel circuits exhibiting component enhancements. One type of metamaterial-based antenna structure is so-called composite right/left-handed transmission line (CRLH-TL) leaky-wave antennas (LWAs). This kind of antenna structure has been shown to offer significant advantages over conventional LWAs. For example, a balanced CRLH-TL LWA is able to achieve continuous backfire-to-endfire frequency-dependent beam scanning with a true broadside beam, good impedance matching over an entire operating band with a simple feeding structure. Utilizing the frequency-space mapping characteristics of CRLH LWAs, the locations of unknown targets can be determined by simply reading the spectral components of the reflected wave. This results in a real time detection scheme since the data acquiring speed is mostly depending on the frequency sweeping speed of signal source, which is typically on the order of milliseconds. Furthermore, the field-of-view of the sensor can be enlarged due to the wide scanning angle provided by CRLH LWAs. Leveraging this unique feature of MTM antennas, various applications including fast 2-D beamforming, real-time remote sensing with large field-of-view that can be used in vital sign detection or motion detection.
