This article presents a dual-band circular N-shaped microstrip patch antenna loaded by a shorting pin and lumped R-C circuit, hence a resonant R-L-C circuit is introduced. Loading by shorting pin excites the zero fundamental mode of the circular patch antenna (TM₀₁₀), and it shifts the first fundamental mode (TM₁₁₀) to higher one. N-shaped microstrip patch antenna is used as a modified circular microstrip patch antenna with reduced size. The proposed antenna is designed and fabricated on two-layered substrate. A comprehensive parametric study has been carried out on values of R and C to optimize the antenna performance. © 2009 Wiley Periodicals, Inc.
