“…After bending the quasi‐transmission line with lower impedance ( Z 2 ), the case is denoted as Bent Monopole. For the conventional monopole antenna with the symmetrical feeding structure, the two horizontal current densities along the edge of the ground plane are mutually cancelled . The resonance is controlled by the guided length of the monopole.…”

“…Because of its low profile, light weight, miniaturized size, easy impedance matching performance, and wide impedance bandwidth, the microstrip monopole antenna has attracted considerable interest for applications in the wireless communication. To enhance the antenna performance, such as impedance bandwidth, sized reduction, and circular polarization, many research studies have been presented . In 2004, a two‐finger monopole antenna was developed by Chen et al The dual‐band performance is shown and easily tuned by changing the finger length, individually.…”

In this article, a coplanar‐waveguide (CPW)‐fed dual‐band antenna for applications of the multisystem integration has been demonstrated. The resonance analysis of the stepped‐impedance (SI) monopole is presented by using the transmission‐line analysis method. The frequency‐response characteristics of the SI‐monopole, such as the resonance condition and harmonic response, are systematically summarized. Furthermore, utilizing several simple techniques, such as bent feeding topology, asymmetric ground plane, and an L‐shaped slot etched in the ground plane, a right‐hand circularly polarized (RHCP) radiating wave at 1.57 GHz and a left‐hand circularly polarized (LHCP) radiating wave at 2.33 GHz are excited for the applications of the global positioning system (GPS) and the satellite digital audio radio (SDAR) service system. After optimization of the geometrical parameters of the proposed antenna, the measured impedance bandwidths of a reflection coefficient less than −10 dB range from 1.40 to 2.98 GHz and from 4.48 to 6.27 GHz, and thus covers most of the commercial wireless communication systems, such as GPS, digital cellular system (DCS), personal communication system (PCS), international mobile telecommunications (IMT)−2000, wireless local area networks (WLAN), and long‐term evolution (LTE) 2300/2600. The measured 3‐dB axial ratio (AR) bandwidths are about 80 MHz at 1.57 GHz and 100 MHz at 2.33 GHz.

“…By etching an inverted U‐shaped strip and an open‐loop design in the ground plane, the 3‐dB AR‐BW was enhanced up to 62% and 65.2%, respectively. Apart from these techniques, the CP bandwidth can also be improved using asymmetrically fed monopole antennas . In the recent literature, an L‐shaped radiator with broadband and unidirectional CP radiation was reported for array applications and a C‐shaped radiator with a modified ground plane in Ref.…”

A novel approach in the design of broadband circularly polarized antennas is presented in this article. The design uses a simple monopole structure with a triangular tapered feed. Right-/left-hand circular polarization (CP) is achieved by protruding L-shaped strip and inverted Lshaped strip along the left/right radiating edge of the monopole. It is proposed that the 3-dB axial ratio bandwidth (AR-BW) can be enhanced when the length of these strips is equal to k g /4 at the center frequency of their respective CP bands. This principle is verified by fabricating the prototype on 1 mm thick FR4 substrate occupying a compact area of 0.19 k 0 3 0.19 k 0 . From the measurement results, it is observed that the overlapped bandwidth (S 11 210 dB and AR 3 dB) of the antenna is 129.04% (1.38-6.4 GHz) which covers all the major WLAN bands including the WiMAX. The proposed antenna has bidirectional radiation characteristics with a broadside gain of 3.49 dBic in the CP band.

This Novel antenna consists mainly of conducting Circular patch with elliptical rings and partial conducting ground plane, with dimensions of 45 mm×31 mm×1.27 mm, Rogers 5880 LZ is selected as a substrate. The impedance bandwidth of the designed antenna is between 3.5 GHz to 9 GHz. The selected partial ground length is 11 mm. VSWR and S11 are obtained for the new antenna through HFSS simulation for different ground plane lengths. Antenna group delay, maximum antenna gain and radiation pattern for this novel antenna are studied and analyzed. The presented antenna achieved the desired BW and the simulated S11 and VSWR are coherent and show unique performance.
