Abstract

Micromachined antennas have been fabricated on GaAs substrates with the thickness of 100 μm. The patch size of a half-wavelength rectangular-shaped antenna has been reduced about 63.8% by fabricating a folded slot antenna with shorting pins. A quarter-wavelength rectangular shaped antenna and the folded slot antenna on COB show the bandwidth of 300 MHz and 350 MHz, respectively and the quarter wavelength antenna on a MLF package presents the bandwidth of 400 MHz. The bandwidth and antenna gain of the half-wavelength antenna, the quarter- wavelength rectangular shaped antenna, and the folded slot antenna have been measured on COB. For the MLF package, the quarter- wavelength rectangular shaped antenna has only been studied
