Recent advancements in techniques to suppress surface wave propagation in microstrip patch antenna

The microstrip patch antenna is extensively used in wireless communication purposes because of its compact size, planar design and economical aspects. Inspite of providing the designer the above mentioned advantages, the antenna suffers from serious hindrances of surface wave propagation and polarization mismatch. In this paper design techniques have been summarized for suppression of surface waves in microstrip patch antenna. Artificial dielectrics designed using EBGs have been proposed. The EBG structures thus proposed can be most suitable to suppress surface wave reduction.
