“…As done with UWB antennas, there are two common techniques to get band notched characteristic to minimize potential interference. One method focuses on loading diverse parasitic elements on the antennas [5][6][7], the other one is embedding various slots [8][9][10][11][12][13]. Both of them can be effectively implemented to get band rejection of multi-band antennas.…”

A printed MIMO antenna with extremely wide-band (EWB) for multi-band wireless applications has been proposed and analyzed in this paper. The designed antenna satisfies the voltage standing wave ratio (VSWR) requirement of less than 2.0 in an extremely wide frequency band ranging from 2.7 GHz to 20 GHz. To enhance the isolation coefficient in MIMO antenna, two parallel strips are added between two radiating elements. Consequently, the mutual coupling coefficient is much below -15 dB for all operating frequency band. In addition, since the bandwidth of this antenna covers frequency bands where several applications and/or services may be simultaneously acting in the considered area, it becomes a very important feature the capability of rejecting the interferences occurring between these systems. In this paper, the introduction of suitable slots as an effective method for sub-band notching has been presented, and, as an example, the WLAN band rejection has been considered in detail. By exploiting the optimization possibilities introduced by the slot structure degrees of freedom, it became possible to obtain the desired band rejection. All the here considered structures have been designed choosing for the substrate the popular FR4, with dielectric constant of 4.4, and thickness 1.6 mm

“…Therefore, an UWB antenna with band reject characteristics is natural choice to overcome this problem. Numerous antennas with band reject characteristics have been reported in the literature . The common practice to achieve band reject characteristics is to etch different types of slots such as U‐shaped, H‐shaped, C‐shaped either in the radiator portion or in the ground plane of UWB antenna .…”

In this article, a study of a triple band notched circular ring monopole ultrawide band (UWB) antenna is presented. The UWB antenna consists of a circular ring radiating patch and rectangular ground plane with two small slots near the feed line for bandwidth enhancement. The proposed antenna can reject worldwide interoperability for microwave access (WiMAX) band (3.3–3.8 GHz), wireless local area network (WLAN) band (5–6 GHz) and X‐band downlink satellite communication band (7.1–7.9 GHz). The WiMAX and WLAN band rejections are realized by introducing two arc shaped elliptical slots and single elliptical split ring slot in the radiating patch, respectively. Furthermore, a pair of rectangular single split ring resonators is used to obtain the rejection of X‐band downlink satellite communication signal. The proposed UWB antenna is fabricated and measured. The measured results are in good agreement with the simulated ones. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:668–672, 2015

“…There are various methods with which we can achieve a band‐notch characteristics in UWB antenna. The most popular approach is to etch different shaped slots such as U‐shaped, H‐shaped, C‐shaped in the radiator portion or in the ground plane of UWB antenna . Conversely, multiple half wavelength U‐shaped slots and complementary split ring resonator were proposed recently to reject more than one of interfering frequency bands .…”

A printed monopole antenna for UWB applications with dual band notch property is proposed in this letter. The UWB monopole consists of modified circular patch with an elliptical slot to reject WiMAX frequencies (3.3–3.8 GHz). The modified ground plane is introduced to attain the wide impedance UWB bandwidth with G‐shaped slot below the feed line to reject 5.15–5.85 GHz WLAN frequencies. The length of embedded slot not only depends on notch frequency and substrate dielectric constant but also depends on substrate thickness and slot width. In this letter, we have presented a technique to calculate accurately the slot length of the embedded slot. The simulated and measured result shows that the designed antenna is expected to be good candidate for UWB applications. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:99–104, 2015
