A Novel Circularly polarized dielectric resonator antenna with Branch-Line Coupler and Log-Periodic Balun
A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
متن کاملCharacteristics and Performance of the North American ALMA Prototype Antenna
The submillimeter antennas of the Atacama Large Millimeter Array (ALMA) have specifications that are beyond the current state of the art in accurate reflector antenna technology. Considering that as many as 64 of these antennas would eventually be needed, the ALMA partners AUI/NRAO and ESO each agreed to acquire a prototype antenna, and subject these to an extensive evaluation program. In this ...
متن کاملALMA Memo 503 Antenna position determination: Observational methods and atmospheric limits
We discuss the accuracy to which ALMA antenna relative positions can be determined via astronomical observations of phase and delay toward multiple strong calibrators. We show that delay induced phase gradients across the bandpass can be used to resolve turn ambiguities so that accurate delays can estimated from the phase. At low frequencies this demands only modest stability of the bandpass ph...

متن کاملALMA Memo #443 ALMA LO Distribution Round Trip Phase Correction
The ALMA requires a coherent local oscillator at each antenna. Due to the long distribution length from central building to each of the antennas, the fiber optic path to each antenna must be stabilized to meet the ALMA specification. A round trip phase correction technique has been adopted to meet these specifications, and that technique is described here. Also, a summary of various techniques ...
