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.

“…Each component was first packaged individually on LCP and characterized. Details of the packaged LNA characterization are reported in [5]. Once a packaging scheme was successfully implemented, both were packaged in series on LCP, shown in Figure 2, and measured.…”

“…In addition, its inherent properties allow it to be processed using standard techniques compatible with printed circuit board manufacturing at lower cost [2]. Furthermore, incorporation of highly functional low power 0.13 μm BiCMOS SiGe circuits on LCP makes this technology [4][5] niche and uniquely positioned compared to other technologies available in the literature [6][7]. It has been successfully shown that the integration of SiGe with radar systems is a viable low cost solution [6].…”

This paper presents an organic, lightweight X-band antenna array with integrated silicon germanium (SiGe) low noise amplifiers (LNA) and 3-bit phase shifters (PS). The SiGe LNAs and PSs were successfully integrated onto an 8x1 lightweight antenna stack-up utilizing a multilayer liquid crystal polymer (LCP) substrate. Successful comparisons of the measured and simulated results verify a working antenna array with a return loss of around 10 dB across the frequency band of 9.25 GHz -9.75 GHz. A comparison of radiation patterns for the 8x1 antenna with integrated SiGe LNA and the 8x1 antenna with integrated SiGe LNA and PS show a 16 dB and 25 dB increase in gain, respectively. The ultimate goal is to develop an airborne X-band radar capable of a beam steering of at least ±40° through utilization of low power highly integrated SiGe electronics on a low cost multi-layer organic platform. This paper represents the first successful demonstration of a building block prototype (i.e., a fully integrated, high gain X-band antenna with SiGe LNAs and SiGe phase shifters) that can be expanded to a complete active phased array for remote sensing applications in X-band.
