Abstract : An inexpensive, flush mounted selectable mode microstrip antenna is frequency-agile and has polarization diversity. The mode, frequency, and polarization of the antenna can be selected by selecting the location of shorting posts in the antenna. The use of switching diodes in place of shorting posts provides the means of electronically switching the mode, frequency, and polarization characteristics of the antenna. The selectable mode microstrip antenna arrays are also provided. The selection of mode, frequency, and polarization can be selected and controlled by digital means such as a computer.
