High gain 60 GHz antipodal fermi tapered slot antenna with sine corrugation

Abstract

ABSTRACT A millimeter‐wave antipodal Fermi tapered slot antenna configured with a new corrugation is presented. The corrugation has a sine wave profile for improved design flexibility and radiation performance. The effect of the sine‐corrugation parameters is presented in detail, and the optimized design is compared with the measured prototype. The antenna is fabricated using a low‐cost printed circuit board process. The measured bandwidth of the antenna covers a wide band (55–65 GHz) with a measured gain of 18.75 dB at 60 GHz. With these features, the antenna is suitable for short‐range wireless communications and imaging applications . © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:6–9, 2015
