that a very coarse grid was used with EF equations, with only two cells between the microstrip and the ground plane and four cells across the microstrip. The maximum error in the 20α60 GHz frequency band is 1.5, 6.7, and 13.5% using the enhanced EF, split-cell, and staircase techniques, respectively

Abstract
An equilateralβtriangular microstrip antenna with reconfigurable polarization capability is proposed. The proposed design is achieved by loading with three Lβtype slits in the triangular patch and three PIN diodes are utilized to switch the slits on or off. According to the states of the diodes, the reconfigurable antenna can produce linear polarization or right hand circular polarization. An antenna prototype is implemented and measured.
