“…A very important conclusion of this study is that the modes of the radiating aperture do not appear as independent or isolated modes, as in [20], but they couple in a coherent way to the modes of the ground plane with the same current variation characteristic, generating a new family of combined radiating modes.…”

“…However, after these works, dating back more than 20 years, little research has been conducted concerning the computation of the CM in slots and apertures. To authors' knowledge, only in [20] and [31], analysis of slotted planar antennas using the Theory of Characteristic Modes has been presented. In [20], the band-notch effect in a U-slotted UWB planar monopole was explained using the CM approach, and in [31], CM were used to obtain circular polarization by modifying the geometry of a U-slot embedded in a microstrip patch.…”

“…In planar antenna design, the inclusion of narrow slots is a common technique used for several purposes such as reducing size [16], creating extra resonances [17], producing dual or circular polarization [18] [19], and generating band notch effects [20]. Also in mobile phone handset antennas the incorporation of slots in the ground plane is a very common technique for getting compact and multiband behavior [21]- [23].…”

Abstract-This paper provides some design guidelines for the excitation of broadband slotted planar antennas, addressing key issues such as coupling, symmetries and multiple feeding. The Theory of Characteristic Modes is used to identify the collection of current modes that exists on these structures, dealing to a valuable understanding of the radiating mechanisms and allowing a more controlled design process. Modal analysis of a circular aperture cut on a finite square ground plane is presented in order to demonstrate that an optimum choice of the feeding mechanism can be made according to the current distribution of the desired modes. Based on the information yielded by this modal analysis, a capacitive-coupled dual-feed circular aperture antenna is presented. This antenna takes advantage of the symmetries of the characteristic currents by making use of multiple feeding, in order to excite only some particular modes. Usage of commonly-fed and differentially-fed configurations enables an increased control of the excitation of modes in the structure. Characteristic modes analysis of the antenna including the feeding structures is presented, showing the influence of the feeding lines in the performance of this type of antennas. A prototype of the antenna has been fabricated and measured. Simulated and measured results are presented, being in good agreement.

Abstract-In this paper, a novel monopole printed fork-shaped antenna for ultra-wideband (UWB) applications with triple band-notched characteristics is presented. The proposed antenna, with compact size of 42 × 24 × 1.6 mm 3 , yields an impedance bandwidth of 3.1-11 GHz for S 11 < −10 dB, except on the notched bands which are obtained by introducing three different types of slots. A U-shaped and two extended U-shaped defected ground structure (DGS) slots give respectively two notched bands, 3.3 to 3.7 GHz for WiMAX and 7.1 to 7.76 GHz for downlink X-band satellite communication systems. Therefore, a semi arc-shaped slot is etched on the radiating patch to notch the band from 5.15 to 5.825 GHz for WLAN applications. The proposed antenna is fabricated and measured.

A novel design of Multi-Input Multi-Output (MIMO) antenna is presented. Pattern and polarization diversity is created using Characteristic Modes (CM) theorem and reduces the envelope correlation and isolation between the ports. So a printed structure consists of two circular patches is proposed for MIMO application. This structure is fed by two slotted coupled feeds configuration. The proposed antenna has been simulated in Ansoft HFSS software and simulation results are presented.
