Abstract :
A closed-form expression is presented for the space wave efficiency of rectangular microstrip antennas. This expression is derived from and compared to numerical results available in the literature. The expression is useful for substrates with relative permittivities between 1 and 12.8 and for the complete range of thicknesses normally used.
