Abstract

The fabrication and performance of miniature high frequency (40-60 MHz) annular arrays is described. The arrays were fabricated using photolithography to define the electrode pattern, and ultrasonic wire bonding to make electrical contacts. The transducers were 2 mm in diameter with seven equal area elements and a centre frequency of 50 MHz. A -6 dB two-way beam width of 75 microns was found at f/2. The radiation pattern decreased smoothly to less than -60 dB at a distance of 550 microns.
