A Dual-Frequency Antenna of Microstrip Characteristics having with Two Thin Symmetrical Rectangular Slots for Wireless Communication Application

For dual-frequency operation, an inset-fed rectangular microstrip antenna (IRMA) loaded with two symmetrical rectangular slots along the non-radiating edges of the radiating element of the rectangular shape is proposed. The proposed antenna has simulated resonance frequencies of 1.89 GHz and 2.41 GHz, allowing it to be used in wireless communication systems. The
$\text{TM}_{10}$
and one strongly activated higher order hybrid mode (
$\text{TM}_{\beta 0}$
Mode-hybrid mode), where
$1 < \beta < 2)$
are the two exciting modes responsible for proposed antenna's dual-band operation.
