“…In an effort to improve the matching of the LH modes and increase the bandwidth of the antenna, a ground plane was used as an additional degree of freedom. A smaller ground plane reduces Q-factors [31] and the introduction of shapes onto the ground plane can improve the matching of antennas [32,33]. The bottom layer of the antenna structure is shown in Figure 8.…”

Abstract-A new compact ultrawideband (UWB) patch antenna based on the resonance mechanism of a composite right/left-handed (CRLH) transmission line (TL) is proposed. The radiating element of the antenna is made from three left-handed (LH) metamaterial (MTM) unit cells placed along one axis, where each unit cell combines a modified split-ring resonator (SRR) structure with capacitively loaded strips (CLS). An analysis of the eigenfrequencies of these unit cells yields one-and two-dimensional dispersion diagrams, which correspond to a one-unit cell antenna and the three unit cell antenna, respectively. A trident feed and a slotted-partial ground plane are used to match the right-and left-handed (RH and LH) modes of the antenna, respectively. In addition, an analysis of the surface current distribution of the antenna shows that slots on the metallic area reduce the Q-factor. This reduction in the Q-factor results in a wide bandwidth of 189% at 3.7 GHz, which spans the UWB frequency range between 2.9-9.9 GHz. The total footprint of the antenna at the lowest frequency is 0.2λ 0 ×0.2λ 0 ×0.015λ 0 , where λ 0 is the free space wavelength. The gain of the antenna ranges between −1 to 5 dB throughout the frequency band.

“…This truncated ground plane and monopole itself actually form an asymmetric dipole system [6]. In this section, a miniaturized folded helical monopole is evolved from the small folded helical dipole in section II by replacing the dipole halves of driven and parasitic arms on one side with a partial ground plane on the bottom.…”

“…It shows stable performance when approaching to other objects [5], and is therefore often preferred in some systems, such as for RFID applications. In addition, monopole antenna is actually an asymmetric dipole system [6] with its dipole half replaced by a vicinity partial ground plane to provide current return path. In convention, the ground plane is usually not counted in the monopole antenna area since it is also necessary and shared with other circuits on board.…”

This paper presents a folding scheme to address fundamental issues of planar electrically small resonant antennas with small radiation resistance, high Q factor, and narrow bandwidth. Two printed folded helical antennas are investigated as examples of small antennas for GSM1800/1900 bands. Dramatic bandwidth enhancements of as much as 66% and 163% are found, respectively, for folded helical dipole and its monopole version over their non-folded counterparts. The proposed folding method facilitates integrated antenna miniaturization with self resonance, sufficient bandwidth, and self impedance matching.

“…Accordingly, designing small antennas can find various important applications. Several promising compact printed dipole antennas with multiband or wideband operations have been reported in the literature [8][9][10][11][12][13]. A wideband dipole antenna using parasitic patches has been presented in [14].…”

A novel compact and multiband dipole antenna with a planar fractal-inspired configuration is presented. Several series capacitances and a parasitic element are employed as loading. Results show that the loading improves the impedance matching and enables the proposed antenna to radiate at multiple frequency bands which are not harmonically related. In addition, the proposed loaded dipole antenna offers a high degree of miniaturization in comparing with the unloaded host dipole antenna. The simulated |S 11 | response of the proposed loaded dipole antenna shows five distinct resonant bands with the center resonant frequencies of 1.
