“…The conventional and effective way to achieve the notch-band is inserting a slot on the patch or on the ground plane [4][5][6][7]. While there are also many other ways to create band-notched characteristics on a UWB antenna, such as using parasitic structures [8][9][10][11][12], embedding a slit in the feedline [13,14], or adding split ring resonator (SRR) coupled to the feedline [15][16][17]. These slots, stubs or branches are in different shapes, but the common point they all share is the same that is introducing a perturbation into the UWB antenna.…”

Abstract-In this study, a novel dual band-notched ultra-wideband (UWB) antenna has been proposed and discussed. The proposed antenna is fed by a micro-strip line and in the square-etched radiation patch a T-shape parasitic stub is attached. On the other hand, a pair of parasitic parallel micro-strip lines are also added on the ground plane, one of which is shorted to the radiation patch by a short-pin through dielectric substrate. The two parasitic units are to achieve bandnotched characteristics at 3.3-3.7 GHz and 5.15-5.85 GHz, respectively. In order to realize impedance matching over the ultra-wideband, two arc-shape cuts are made symmetrically at the junction of feed-line and radiation patch. The simulated and measured results, including return loss, radiation pattern, group-delay and peak gains are in good agreement with theory analysis which validates our design concept.

“…The inductance L produced by the straight inductor can be calculated by Eq. (2) as stated in [8][9][10][11][12][13], and more specifically in Eq. (1) of [7] where I L is the inductor length, W 1 is the inductor width, and t is the metal thickness as shown in Figure 1(b).…”

“…Thus, the structure can be treated using microstrip transmission line theory, with as the length of the structure. The resonant frequency of the resonator is given in [12], also stated as Eq. (7) of [7] and it's dependent on, the inductor strip L, the capacitive inductance from the IDC (the length of the finger, the line width of the finger), and the pad capacitances, C p where C is the IDC defined by Eq.…”

Abstract-In this paper, a simple-fed, low profile, 9 × 10 elements quasi-lumped planar antenna array is presented. The proposed resonator employs a quasi-lumped element resonator that uses interdigital capacitor (IDC) in parallel with a straight strip inductor shorted across the capacitor. The array elements were designed and then excited by a feed network of four coaxial probes situated at the bottom plane but separated from the ground plane using a plastic material. The entire array is divided into four sub-array lattices of 5 × 5 elements and excited by a coaxial probe located at the centre of the sub-arrays antenna structure, thus exciting the centre resonator who in turn excites the neighbouring elements via proximity coupling. The probes are connected based on Wilkinson power divider principle to provide in-phase excitation. An explicit method is introduced to quickly obtain the array factor (AF) characteristics for such proximity coupled rectangular planar array. Radiation pattern and the array factor are presented, and are further compared with those obtained by the simulation and experimental results. The proposed antenna comprises 9 × 10 elements array, each of which is 5.8 × 5.6 sq. mm in size, and the entire antenna structure is about 120 × 80 sq. mm.

“…Some other techniques, based on the employment of reactive loads and reactive slots on the patch, instead, do not degrade the compactness of the component, but suffer of limited flexibility, making the design of high-performing devices with enhanced features rather difficult [10][11][12][13][14]. Finally, other techniques are based on band-notched filters, which allow keeping the antenna size rather small, enable the broadband behaviour, but usually exhibit asymmetric and strongly irregular radiation patterns [15][16][17]. Polygonal patches have been suggested by the authors as good candidates for telecommunication applications, since they may provide antennas with the required broad-band behaviour and multi-frequency operation, without increasing the space occupancy [18][19][20][21][22][23].…”

Abstract-In this paper, extending the design technique presented by the authors in a previous work, we propose the study of a new family of polygonal patch antennas for portable devices of communication systems. Such antennas are suitable to be mounted in modern terminals, enabling wideband/multi-frequency operation and new multimedia features. The desired electromagnetic behaviour of the proposed radiators is obtained by adding either shorting posts, properly located between the polygonal patch and the ground plane, or circular slots, drilled at the appropriate position on the patch surface. Circular slots are also useful to easily accommodate a photo-camera in the terminal, in order to enable multimedia services and video calls. Some practical layouts of polygonal patch antennas to be used in: a) modern PDAs and Smart Phones integrating cellular phone operation and wireless functionalities; b) UMTS terminals integrating also GSM functionalities, are, finally, presented. The effectiveness of the proposed designs is confirmed through proper full-wave numerical simulations.
