The 2021 Asia Pacific Microwave Conference (APMC 2021) will be held in Brisbane, Australia, from the 28th of November to 1st of 
December 2021 (dates fixed and confirmed). The organising committee is monitoring the COVID‐19 situation and will consider hybrid 
or online format if required. 
APMC2021 is organised by the Australian Chapters of the IEEE MTT‐Society and sponsored by the IEEE MTT Society. Papers submitted 
to APMC2021 will be peer reviewed. The conference will cover the entire scope of microwave engineering, including RF/microwave, 
antennas & propagation and EMC/EMI. Prospective authors are invited to submit original papers on their latest research results. All 
papers presented at the conference will be submitted to IEEE Xplore for publication. Proposals for special sessions, workshops and 
tutorials are also solicited.
