Coupled‐line proximity‐coupled microstrip linear array antenna for millimetre‐wave applications

Investigation into Series-Fed Microstrip Patch Arrays at 26 GHz, 28 GHz and 48 GHz – Design, Simulation and Prototype Tests

“…The tapering of the element widths in the array offers a mechanism to shape the beam profile [6] - [9] and control SLL. The power feeding mechanisms to the patches can be implemented by wide variety of approaches [5], [10] - [11]. In this paper a simple transmission line is used to interconnect the patches.…”
