“…As discussed in [18] and [19], this is conventionally done by calculating the noise figure, , and figure-of-merit , referenced at the output of the antenna. In this work, these parameters were calculated using (2) and (3) where is the standard reference temperature 290 K, is the directivity of the antenna, and and are the Ohmic loss and mismatch loss, respectively, in the feed line between the antenna element and LNA. From these equations, it is clear that when the LNA gain, , is sufficiently large, the feed line loss and LNA noise figure will have the most effect on performance and the components following it will have a negligible effect.…”

This paper presents for the first time an X-band antenna array with integrated silicon germanium low noise amplifiers (LNA) and 3-bit phase shifters (PS). LNAs and PSs were successfully integrated onto an 8 2 lightweight antenna utilizing a multilayer liquid crystal polymer (LCP) feed substrate laminated with a duroid antenna layer. A baseline passive 8 2 antenna is measured along with a SiGe integrated 8 2 receive antenna for comparison of results. The active antenna array weighs only 3.5 ounces and consumes 53 mW of dc power. Successful comparisons of the measured and simulated results verify a working phased array with a return loss better than 10 dB across the frequency band of 9.25 GHz-9.75 GHz. A comparison of radiation patterns for the 8 2 baseline antenna and the 8 2 SiGe integrated antenna show a 25 dB increase in gain (1 ). The SiGe integrated antenna demonstrated a predictable beam steering capability of 41 . Combined antenna and receiver performance yielded a merit of 9 1 dB K and noise figure of 5.6 dB.

“…New materials are being explored for advanced antenna design that are thinner, lighter and have better high frequency characteristics, making a wider range of applications possible [2]. In recent years, Liquid Crystal Polymer (LCP) has been established as an exceptional microwave organic dielectric due to its key performance and packaging advantages.…”

“…The drawback of such technologies is that they often require an expensive packaging and chip integration. Recently, a flexible printed conformal phased array antenna was introduced by using active membrane phased-array for radar applications [17]. Another recent advance in the development of lightweight flexible PAAs is based on a Liquid Crystal Polymer (LCP) substrate [18].…”

Abstract-A fully printable and conformal antenna array on a flexible substrate with a new LeftHanded Transmission Line (LHTL) phase shifter based on a tunable Barium Strontium Titanate (BST)/polymer composite is proposed and computationally studied for radiation pattern correction and beam steering applications. First, the subject 1 × 4 rectangular patch antenna array is configured as a curved conformal antenna, with both convex and concave bending profiles, and the effects of bending on the performance are analyzed. The maximum gain of the simulated array is reduced from the flat case level by 34.4% and 34.5% for convex and concave bending, respectively. A phase compensation technique utilizing the LHTL phase shifters with a coplanar design is used to improve the degraded radiation patterns of the conformal antennas. Simulations indicate that the gain of the bent antenna array can be improved by 63.8% and 68% for convex and concave bending, respectively. For the beam steering application, the proposed phase shifters with a microstrip design are used to steer the radiation beam of the antenna array, in planar configuration, to both negative and positive scan angles, thus realizing a phased array antenna.

The performance of spaceborne synthetic aperture radar (SAR) is limited by the size and therefore the areal density of the antenna array. Conventional arrays consist of radiating elements mounted on hinged panels that are relatively heavy. In order to produce larger arrays capable of operating at higher altitudes, or to support comparable SAR payloads on smaller spacecraft, a lighter structure such as one using membranes must be used. Membrane antenna arrays have been developed, but deployment remains a challenge. This paper describes possible techniques to package and deploy membrane structures that can support these antenna arrays.
