Effect and Correction of Unequal Cable Losses and Dispersive Delays on Delay-and-Sum Beamforming
Radio frequency beamforming arrays may be vulnerable to distortion caused by cables, especially when the distortion is unequal between sensors. This paper analyzes the effects of unequal per-sensor cable distortion on delay-and-sum beamforming, and proposes methods to equalize the responses using digital FIR filters. A simplified version of the LWA1 radio telescope, consisting of 256 isotropic ...
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 کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...
متن کاملFIR-filter based RF-beamforming network for wideband and ultra wideband antenna arrays
In this paper, a wideband electronic beamforming concept applicable for UWB short pulse systems is derived and experimentally demonstrated. In particular, a Finite Impulse Response (FIR)-filter based beamforming network is configured such that an antenna array yields a desired radiation pattern within a predefined frequency range. An experimental verification of a wideband transmission system i...
متن کاملTDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire
Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...
