Abstract

In this paper, a v-band MMIC self oscillating mixer active integrated antenna using a push-pull patch antenna is presented. The SOM AIA is based on the coupled active parallel feedback oscillator. By using a push-pull patch antenna, the isolation between balanced RF input and in-phase local oscillation is established. Furthermore, since the push-pull patch antenna has very low radiation efficiency for the in phase signal injection, the LO radiation was efficiently suppressed. The circuit is fabricated using the 0.15μm pHEMT process on 100μm thick GaAs substrate. The local oscillation frequency is 58.46GHz. The LO radiation level is measured to be lower than -50dBm at distance of 1cm. The circuit shows about -18.9dB effective isotropic conversion gain at 1.54GHz IF.
