Two concentric circular split rings embedded onto a rectangular monopole radiator is designed for 3.5 GHz (WiMAX) applications. The antenna is designed on a 20 × 20 × 1.6 mm3 FR4 dielectric with a slotted ground plane structure. The monopole is designed as a λ/2 radiator. The addition of splits in the two concentric circular rings supports in bringing down the frequency to a lower band of 3.5 GHz, which is nearly half of the monopole’s resonance. This yields a miniaturization of about 50%. The slotted ground plane aids in achieving wider impedance matching at the desired mode of operation. The antenna radiates uniformly well in all directions with a peak gain of 1.5 dBi, making it suitable for wireless communication devices.
