- Abstract
This work proposes an element with a 1-bit phase resolution that operates in both reflection and radiation modes. The 1-bit phase responses in two operating modes can be realized by switching the states of three integrated p-i-n diodes. The array composed of the elements can be excited as both a reflectarray (RA) by the external feed in space and a phased array (PA) without phase shifters by the integrated feeding network at its bottom. Drawing inspiration from the RA, the feeding network introduces initial phase distributions irradiated by a hypothetical spatial feed above the PA to mitigate the grating lobes of the 1-bit PA. An electronically reconfigurable array antenna prototype composed of 8
