Microstrip patch antennas are employed in a variety of commercial and military applications due to their versatility, low profile, and ability to be easily fabricated. In this thesis, a microstrip patch antenna is made from artificial magnetic conductor (AMC) unit cells that excite the dominant transverse electric (TE) mode via an L-strip coplanar with the AMC patch layer. Integration of the L-strip into the unit cell layer of the AMC patch and the ground layer of the AMC patch is investigated and full-wave analyzed. To improve gain radiation pattern symmetry about the broadside direction, the AMC patch is shifted laterally with respect to the ground plane. Four antennas are simulated, two of which are fabricated and measured. The measured results are in good agreement with the simulations; therefore, the coplanar L-strip excitation technique successfully eases fabrication for TE-mode antennas, which require significantly less surface area than TM-mode microstrip patch antennas.
