Cylindrical-rectangular microstrip antenna [PDF]

IEEE Transactions on Antennas and Propagation, 1983
Resonant frequencies f_{r} of a cylindrical-rectangular microstrip antenna are theoretically calculated. Comparison is made to f_{r} for a planar rectangular patch antenna, including the simplest planar patch modes having no field variation normal to the patch surface.

Small Microstrip Patch Antennas

Electronics Letters, 1995
As stated in Chapter 1, one of the many advantages of microstrip patch technology over its competitors is its low profile and hence small volume. Another key advantage of this printed antenna is the relative ease in which it can be connected to the feed network, as was highlighted in Chapter 2.
