Abstract :
The design and analysis of a series-fed, foldable microstrip array antenna for radiometric applications is presented. The array antenna is composed of two equal sub-arrays. Each sub-array consists of a series of patches connected together through segments of microstrip lines. The sub-arrays are fed 180 degree out of phase to ensure a symmetric radiation pattern. The design approach, is accomplished using the IE3D code that utilizes the method of moments. All experimental and simulated data are presented and discussed.
