A leaky‐wave antenna (LWA) is designed using quarter‐mode substrate‐integrated waveguide (QMSIW). The LWA unit cell is miniaturized because the QMSIW size is quarter of SIW cavity. A traveling wave leaks away from open edges of the QMSIW. Its performance is verified with full‐wave simulation and measurements. The main beam direction varies from 0 to 28° when frequency varies from 12.5 to 15.4 GHz. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1234–1236, 2015
