“…To achieve a large delay time on a compact chip size, several technics have been proposed. MEMS based [9,10,11,12] and optical [13,14,15] TTDLs could offer favorable performance. However, they often need complicate process and are not compatible with standard IC technologies.…”

True time delay lines and phase shifters are widely used in RF timed/phased array systems. Conventional delay lines and phase shifters often associate with reflection type circuits or distributed (periodically loaded) transmission lines. In this paper, we propose a new type of distributed circuit which composed of uniform transmission lines built on integrated Schottky active layer. A bi-functional chip is designed based on the new distributed structure. An Archimedean spiral topology is adopted to reduce the chip area. Theoretical analysis of the design method and circuit parameters is performed and a miniaturized prototype is implemented with p-HEMT technology to validate the design theory. Measurement results shows that this chip could work as either an areaefficient true-time delay line or a low-voltage phase shifter over the bandwidth 11-15 GHz. As an area-efficient true-time delay line, this chip provides 82.1 ps delay time per square millimeter when the biasing voltage fixed at −1.4 V. As a low-voltage phase shifter, this chip provides 26.43°p hase shift per volt when the biasing voltage sweeps form 0 V to −1.4 V.

“…Unlike the phase shifter, the TTD has a negatively increasing phase performance. In figure  is time delay, f is frequency and  is phase [9][10][11][12][13][14].…”

“…However, because of the complexity, large volume and high cost, the further application in some special area has been limited, such as in space and in ammunition [1,2]. RF MEMS phase shifters and switches, as the critical elements in PAAs, which have exhibited excellent characteristics including small volume, low insertion loss and low dc power consumption compared to the GaAs based MMIC counterparts, have been demonstrated in [3,4,5]. With the advent of RF MEMS phase shifters and switches, there should be considerable business interests in the development of MEMS-based phase array antenna.…”

A two-dimension scanning of phased array antenna has been presented. Aperture coupled microstrip patch antenna (ACMPA) elements are used to form a 2 × 2 array operating at 20 GHz. The array is monolithically fabricated with RF MEMS switches by using surface micromachining and anodic bonding process. The main beam can steer in two dimensions when the phase shifters are on the different state. The measurement results show that the array can complete a beam steering angle of approximate ²30°i n both E-plane and H-plane, and the highest gain is 9.5 dB.
