antenna prototype (IMAGE) Penn State Caption Researchers illustrated and designed a circular, iris-shaped patch antenna prototype using commercial electromagnetic simulation software. Though the prototype is only slightly larger than a human palm, the technology can be scaled to the integrated circuit level for higher frequencies or increased in size for lower frequency applications, according to researchers.
