“…By properly choosing of α and adjusting the length of the two dipoles, circular polarized radiation in the operation frequency band is obtained. In addition, the tapered structure leads to a wide impedance bandwidth [8][9][10][11][12][13][14][15][16][17]. Similar to the results in [8], the proposed tapered meander-line bowtie structure has large input resistance than other bent antennas such as the general meander, the zigzag, and the sinusoidal, which make it easy to match.…”

Abstract-A novel miniaturized circularly-polarized antenna is presented. By using tapered meander-line structure, the designed antenna has a size reduction rate of 96% compared with a traditional turnstile dipole antenna. The unequal lengths of the two meanderline dipoles are properly adjusted to achieve a circularly polarized radiation. Furthermore, the impedance matching is effectively realized by a lumped matching network. A prototype of the antenna with a size of 64 × 64 mm 2 has been implemented and tested. Good agreement is achieved between the simulated results and the measured results, which shows that the axial ratio is less than 3.0 dB and the VSWR less than 2.0:1 in the frequency range of 450 ± 1.5 MHz.

“…Printed slot antennas are unique relative to microstrip antennas as they generally provide wider bandwidth, ease of impedance matching, and their radiation can be designed to be either bidirectional [4,5] or unidirectional [6]. The simple uni-planar configuration also makes them suitable for various applications [7][8][9].…”

Abstract-In this work, a quad-band omnidirectional slot antenna array is proposed. The structure consists of two closely-spaced radiating elements fed using coplanar waveguide (CPW) line. This combined structure is then integrated in a tapered slot etched on the antenna to enable operation in four frequency bands (0.8, 1.8, 2.6 and 3.45 GHz) for LTE and WiMAX applications with at least −10 dB of reflection coefficient. The antenna dimensional parameters are also studied to understand its behaviour and effects on its performance in facilitating the optimization process. Measurements of the fabricated antenna on a low-cost FR4 substrate validate its operation centred at 0.845 (from 0.77 to 0.92 GHz), 1.745 (from 1.59 to 1.9 GHz), 2.655 (2.59 to 2.72 GHz) and 3.49 GHz (from 3.28 to 3.7 GHz). Meanwhile, simulated and measured radiation patterns of the proposed antenna in all bands agree well and are omnidirectional, making is suitable for application in mobile terminals.

“…Slot dipole antennas fed by coplanar waveguide (CPW) have a number of appealing characteristics that include relatively low feed line dispersion and losses at millimeter-wave frequencies, ease of integration with circuit components due to the uniplanar configuration, and considerably wider impedance bandwidth than microstrip patch antennas on comparable substrates, e.g., (Miao et al, 2000). In the sub-millimeter and millimeter-wave ranges, CPW-fed slots have been used to feed dielectric lens antennas (Focardi et al, 2002); arrays of CPW-fed slots are also expected to be used for space applications (Neto et al, 2003).…”
