摘要：An inexpensive, flush mounted microstrip antenna which is frequency agile and has polarization diversity. The frequency and polarization of the antenna can be lected by lecting the location of shorting posts in the antenna. The u of switching diodes in place of shorting posts provides the means of electronically switching the frequency and polarization characteristics of the antenna. Frequency- agility provides frequency scannable microstrip antenna arrays which also have polarization diversity. Frequency-agility, polarization diversity and frequency scannable arrays are controllable by digital means such as a computer.
