Zahra Esmati

Zahra’s career story

Antennas are everywhere. There are tiny ones in every mobile phone and laptop, and in the hardware that helps them connect to wi-fi. They are in the security tags that prevent shoplifting in stores. They’re in medical devices that can detect cancerous tumours. And, of course, there are the big ones that capture signals from satellites in space.

Zahra Esmati has been fascinated by antennas ever since she studied telecommunications back in her home country of Iran. Now, she is an antenna engineer with Fleet Space Technologies. Here, she works on antennas for nanosatellites for Internet of Things (IoT) applications.

Fleet Space is also a part of the Seven Sisters program, an Australian lunar exploration mission supporting NASA’s Artemis program. The program is designed to learn more about the presence of water on the Moon, ahead of sending the first woman and next man to the lunar surface in 2024, and establishing a sustainable human presence there by the end of the decade.

“I remember it was so exciting when we were selected,” Zahra says. 

“We were like, oh, we're going to the Moon!”

Laying the foundations 

Zahra’s interest in antennas took her to several other research areas before she landed in the space industry. Her masters at Western Sydney University looked at the use of antennas in infrastructure health monitoring. Sensors are embedded in the concrete of large structures like bridges or buildings to monitor damage. However, the batteries in the sensors only last a few years. Zahra’s project explored using antennas to recharge the batteries wirelessly to keep the sensors running longer.

Zahra also worked as a research engineer at WSU for a number of years. She worked on a bionic voice project, an electronic prothesis to help people who have physically lost their voice. Her plan was to stay at WSU and complete a PhD in biomedical engineering. However, an exciting scholarship offer from the University of New South Wales proved too good to miss.

One step closer to space

She packed up and moved to Canberra to start a different PhD – one that would bring her closer to a space career. This project looked at electrically small array antennas for high power microwave applications.

“I always thought I’d like to work in space. I knew it would be difficult, but I believe in never giving up and never letting the ups and downs of life stop me.”

Zahra moved again in 2020, relocating to Adelaide to work at Fleet Space. 

Next stop: the Moon

“Communicating to and from space is a challenging endeavour. It looks easy in the movies. Astronauts on far off planets video chat with family on Earth with high quality and no delay. But does it match reality? Not really! I like the challenge and this is one of the reasons I love working in the space industry”.
