A design concept for an MMIC microstrip phased array [PDF]

open access: yes
A conceptual design for a microstrip phased array with monolithic microwave integrated circuit (MMIC) amplitude and phase controls is described. The MMIC devices used are 20 GHz variable power amplifiers and variable phase shifters recently developed by ...

A dual frequency microstrip antenna for Ka band [PDF]

open access: yes
For fixed satellite communication systems at Ka band with downlink at 17.7 to 20.2 GHz and uplink at 27.5 to 30.0 GHz, the focused optics and the unfocused optics configurations with monolithic phased array feeds have often been used to provide multiple ...

Large phase-shifting channel spacing phased array antenna with triangular grid

open access: yesTongxin xuebao
Phased arrays with large channel spacing could reduce costs and improve compatibility, but they significantly limit scanning performance. A phased array antenna with a channel spacing of λ0 was designed.
