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 (TM 010 ), and it shifts the first fundamental mode (TM 110 ) 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.
