The design and realization of a compact coplanar waveguide (CPW) fed ultrawideband (UWB) antenna having dual-notched bands is presented in this article. The antenna possesses on demand notch bands at 4 to 5.78 GHz and 6.83 to 8.22 GHz. The presented design consists of a single iterated octagonal patch antenna designed on cheap FR4 substrate. The stub is utilized to achieve a wide impedance matching of 7.33 GHz (3.2-10.5 GHz), while the notch-bands are realized using split ring circular slots. These notch-bands are controlled independently without affecting the overall performance of the antenna. Simulated and measured results showed that the antenna offers excellent performance with an overall size of 20 × 23 mm2, high efficiency of more than 90%, and a nearly omnidirectional maximum gain of 4.8 dBi. The performance of the proposed antenna is better than the antennas presented in the literature in term of size, stable gain, and independently controllable notch bands. Besides these advantages, the compact size allows the antenna to integrate into small devices easily and help manufacturers to produce a massive number of antennas comfortably.
