Null Steering GPS Array in the Presence of Mutual Coupling
A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...
متن کاملUltra Wideband Monopole Antenna Excited by a Capacitive Coupling Feed with Double Band Notch Function
This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antennas truncated ground-plane incorporates a central notch. This modification significantly improves the antennas impedance bandwidth by 118% over an ultra-wideband frequency range. T...
متن کاملDouble resonant absorption measurement of acetylene symmetric vibrational states probed with cavity ring down spectroscopy.
A novel mid-infrared/near-infrared double resonant absorption setup for studying infrared-inactive vibrational states is presented. A strong vibrational transition in the mid-infrared region is excited using an idler beam from a singly resonant continuous-wave optical parametric oscillator, to populate an intermediate vibrational state. High output power of the optical parametric oscillator and...

متن کاملCPW Fed Double T-Shaped Array Antenna with Suppressed Mutual Coupling
A compact CPW-fed double T-Shaped antenna is proposed for dual-band wireless local area network (WLAN) operations. For the proposed antenna, the -10 dB return loss bandwidth could reach about 25.5% for the 2.4 GHz band and 5.7 % for the 5 GHz band, which meet the required bandwidth specification of WLAN standard. To reduce the mutual coupling and get high isolation between two dual-band antenna...
