Antennas and Propagation, IEEE Transactions on Volume 57, Issue 12, Date: Dec. 2009, Pages: 3972-3975 Digital Object Identifier 10.1109/TAP.2009.2033481 Summary: The goal of this article is to present an analytical solution to the feeding mechanism for a microstrip patch antenna fed by a vertical probe. The feeding mechanism employs a circular capacitive structure to improve the impedance matching, specificall...
