A New high-Gain Microstrip Yagi Array Antenna with a High Front-to-Back (F/B) Ratio for WLAN and Millimeter-Wave Application. Gerald R DeJean,Manos M. Tentzeris. IEEE Transactions on Antennas and Propagation . 2007G. R. DeJean, M. M. Tentzeris, "A new high-gain microstrip Yagi array ...
A new printed microstrip Yagi array antenna is proposed that can achieve a high gain and low backside radiation for various applications up to the millimeter-wave frequency range. The high front-to-back (F/B) ratio (up to 15 dB) is attributed to the constructive interference that takes place...
The stripline aperture coupling structure is introduced to lower the back radiation of a broadband low-profile metamaterial mushroom antenna. Compared to the feeding structure of a microstrip line aperture coupling, the stripline aperture coupled mushroom antenna exhibits a front-to-back ratio enhancement...

Realtek S1220A. It features an unprecedented 120 dB signal-to-noise (SNR) ratio for the stereo line out and a 113 dB SNR for the line in, providing pristine audio quality. Additionally, an impedance-sensing circuit automatically adjusts gain to ensure an optimal volume range for your ...
Rynk. (B) ECS. Most standalone stacking conveyors allow material to be heaped in stockpiles that are up to 15 m (50 ft) tall. Increasing the height of stockpiles is an effective way to store large volumes of finished product or amendments within a relatively small area. The ratio of ...
