A planar Vivaldi array antenna that can achieve four sector radiation patterns in the azimuth plane is presented. Prototypes of the proposed antenna operating within 3.1-10.6 GHz for ultrawideband applications were designed and constructed. Measured and simulated results are used to demonstrate the performance of the antenna. ABSTRACT: A Ka-band low noise amplifier (LNA) using three cascaded stages was designed and implemented in a standard 0.18 m CMOS technology. The fabricated Ka-band LNA achieves power gain (S21) above 12 dB from 30 to 32 GHz and a minimal noise figure of 5.2 dB at 31.5 GHz. The three cascaded stages LNA consume 15.58 mA from 1 V power supply. Compared with the recent published literatures, this LNA operates at the highest frequency ever reported by standard bulk 0.18 m CMOS process.
