In this letter, the design, fabrication, and measurement of a 60-GHz printed antenna with inkjet technology over a flexible substrate is presented. The antenna is a coplanar square monopole with omnidirectional radiation characteristics. We especially measured a 68% total efficiency and a maximum realized gain of 1.8 dBi. This study demonstrates the inkjet technology being a competitive solution for efficient radiating elements at millimeter- wave frequencies.
