What is Triple band-notched UWB CPW and microstrip line fed monopole antenna using broken ∩-shaped slot about?

This paper describes a compact ultra-wideband CPW and microstrip line printed monopole antenna with multi band-rejection characteristics. The small antenna fed by CPW and microstrip line has small volume of 44 mm × 12 mm × 0.8 mm. By adding broken ∩-shaped slot on the tapered radiating patch, the antenna provides band-rejection characteristics. The center frequency of three notched bands centered on 2.4, 3.8, and 5.5 GHz can be adjusted by modifying the length and width of the inserted slot. Good agreement is achieved between the simulated and measured results. The measured impedance bandwidth of the proposed antenna ranges from 2.2 to 11.3 GHz for VSWR ≤ 2, excluding the rejection bands. The omnidirectional radiation patterns of the fabricated antenna are presented, which show that the designed antennas are good candidate for various UWB applications. The measured gain variation is less than 3 dB over the operating frequency band.
