The Square Kilometre Array (SKA) will be the most sensitive radio telescope ever built. It is divided into three operating bands. Sparse aperture arrays (SKA-low) are used at the lowest operating band of 70 - 450 MHz. The International Centre for Radio Astronomy (ICRAR) is exploring conical spiral antennas as one candidate antenna design for SKA-low. One of the attractive features of the conical spiral antenna is its frequency-stable impedance. This helps in matching it to external components such as a low-noise amplifier (LNA). A prototype LNA based on GaAs HEMT technology that might be suitable for the conical spiral antenna has been evaluated. Presented in this paper is the current design path for a conical spiral antenna with attached LNA. © 2011 Engineers Australia. | |
