Following on the post about the basics of microstrip patch antennas, this post addresses the methods of feeding the RF signal to the antenna. A number of popular methods are discussed and described. The fundmentals are quite clear. A follow on post to this one is the analysis and description of the input impedance of the microstrip patch antenna to be posted shortly. Interested readers can download the article from the Signal Processing Group Inc, website by clicking on the menu item ” complementary”, and choosing the appropriate link.

A rectangular patch antenna using PCB and microstrip technology is a very useful component to develop if a simple, small footprint, easy to use antenna is desired. As the name implies it is a rectangular structure formed on a top PCB layer with a ground plane under it. A recent set of white papers released by Signal Processing Group Inc., address this antenna design. The first of these is now accessible from the SPG website by using the “complementary” menu item. It is free for use. The rest of the white papers will be posted in subsequent posts. Interested readers may follow these as and when they are posted. Keep in touch!

Following an article published recently in the Signal Processing Group Inc., website on parabolic reflector antennas, this post deals with describing typical specifications of such an antenna. Interested readers may access the white paper from the SPG website by using the “complementary” link.
