high bandwidth microstrip patch antenna design




The bandwidth of an antenna refers to the range of frequencies over which the antenna can operate correctly. The antenna’s bandwidth is the number of Hz for which the antenna will exhibit an SWR less than 2:1. The bandwidth can also be described in terms of percentage of the center frequency of the band.

Bandwidth of antenna can be increased by various methods such as by increasing the thickness of substrate with low dielectric constant, by probe feeding, by cutting slot, by cutting notches and by different shapes of antenna.
