A compact coplanar waveguide fed UWB (ultra-wideband) antenna with triple band-notched characteristics is presented. The rectangle radiation patch is used in the new design, and the bandwidth of the UWB antenna is extended by using circle corner for the rectangle cut from the ground. A parasitic element is added, whereas an inverted U-shaped slot is cut on the top of the CPW ground plane and a U-shaped slot is cut on the rectangle radiation patch. As a result, a triple band-notched characteristic is obtained, by which the potential interference between UWB and WLAN (Wireless Local Area Networks), C-band and X-band systems can be effectively reduced.

A complete design method for a compact uniplanar ultra-wideband antenna with subband rejection capability is presented. A slotline resonator is incorporated in the coplanar waveguide feeder of the antenna to act as a bandstop filter, hence enabling the rejection of any undesired band within the passband of the antenna. Two samples of the proposed antenna were designed and manufactured. One of the developed antennas does not contain a resonator, whereas the other contains a slotline resonator. The designed antennas feature a compact size of 27 mm×27 mm. Results of the simulation and measurement show that the designed antennas have a bandwidth from 3 GHz to more than 11 GHz. The results also reveal that the use of the resonator in the feeder of the antenna efficiently rejects any undesired subband, such as the 4.9–5.9 GHz band assigned for IEEE802.11a and HIPERLAN/2. The gain of the antennas with the resonator is about 2.2 dBi at the passband, while it is less than −8 dBi at the rejected subband.

<span>Notches loaded on a patch antenna can affect significantly on </span><em><span lang="AR-SA">‎</span></em><span>the antenna impedance matching. Therefore, notching technique is an efficient way to reduce </span><em><span lang="AR-SA">‎</span></em><span>the electromagnetic interference with unwanted bands. In this paper, a </span><em><span lang="AR-SA">‎</span></em><span>novel inverted diamond</span><em><span lang="AR-SA" dir="RTL">‏-‏</span></em><span>shaped closed-end slot on a substrate and </span><em><span lang="AR-SA">‎</span></em><span>vertex-fed printed hexagonal patch ultra</span><em><span lang="AR-SA" dir="RTL">‏-‏</span></em><span>wideband antenna is proposed for high-frequency band rejection. This antenna is fed using </span><em><span lang="AR-SA">‎</span></em><span>coplanar waveguide, and it is </span><span lang="EN-GB">optimised</span><span> by veering several patch </span><em><span lang="AR-SA">‎</span></em><span>parameters which further improved the inter bandwidth at both the </span><em><span lang="AR-SA">‎</span></em><span>lower and upper bands. However, the centre-notched band is shifted </span><em><span lang="AR-SA">‎</span></em><span>from 6 GHz to 7.5 GHz by cutting the inverted diamond shape in a </span><em><span lang="AR-SA">‎</span></em><span>special process. The developed ultra-wideband antenna is verified by </span><em><span lang="AR-SA">‎</span></em><span>comparing the simulation results with the measurement results. The </span><em><span lang="AR-SA">‎</span></em><span>measured results with a fractional bandwidth of 133% have a good </span><em><span lang="AR-SA">‎</span></em><span>agreement with the simulation results 146%. Moreover, the measured radiation showed omnidirectional patterns</span><em><span lang="AR-SA">‎</span></em><span lang="EN-GB">.</span>
