“…The length of a conventional closed-slot antenna is usually half wavelength; however, the length of an open-slot antenna is usually about a quarter-wavelength [8,9]. Many works for CP open-slot antennas have been proposed [10][11][12][13][14][15]. In [11], an L-shaped open-slot antenna with CP is first presented to operate at the GPS band of 1.57 GHz.…”

Abstract-In this paper, a simple broadband circular polarization (CP) V-shaped slot antenna is developed. The CP antenna consists of Z-shaped feedline with a stub and a patch, and symmetrically etched two right-angled V-shaped slots (an open slot and a closed slot) along the center line. The stub is introduced for multi-resonances to obtain broadband. The broad CP and impedance bandwidths overlap by the symmetrically etched right-angled V-shaped closed slot along the center line and the Z-shaped feedline placed in a proper position. The measured results show that the proposed antenna has a broad overlapped 3-dB axial ratio (AR) bandwidth and −10 dB impedance bandwidth of 71% (2.19-4.6 GHz).

“…Another method to enhance the impedance BW and ARBW is to use monopole or slot antennas. Slot antennas having an L-shape and fed by a Cshaped feed-line can also generate CP radiation [6] where 23% ARBW was reported covering the global positioning systems (GPS) band. In [7] a tilted monopole antenna fed with a microstrip feed-line having a partial ground plane with a triangular slit was presented, offering an overall ARBW of 59.1% to operate for the GNSS system of Beidou in China.…”

This paper presents a new wideband and circularly polarised (CP) slot antenna realised by using an L-shaped feed underneath the cross-slot antenna, and tapered to the conventional microstrip feed-line. The proposed antenna is fabricated with an area of 75 × 80 mm 2 . The simulated results showed that the antenna had an impedance matching bandwidth of 34% from 1.3 to 1.83 GHz, and an axial ratio (AR) bandwidth of 20% from 1.36 to 1.66 GHz. A maximum gain value of 3.4 -3.8 dBi has been achieved within the operating band. The proposed antenna is of a simple and single-substrate structure, suitable for the Global Navigation Satellite Systems (GNSS) application. The impedance bandwidth and radiation patterns have been confirmed by measurement.

“…However, antenna configurations of these designs are so complicated that they lead to complexity in antenna design and fabrication. An L-shaped wide-slot circularly polarized antenna has also been introduced [8][9][10][11]. In [8] and [9], the CP operation was achieved by introducing a feedline perturbation in the form of an L-probe feed connected to an L-shaped slot through a shorting via connector.…”

Abstract-A compact circularly polarized antenna using a wide L-shaped slot and a microstrip feedline is proposed. The measured results demonstrate that the antenna has an axial ratio (AR) < 3 dB bandwidth ranging from 5-8.5 GHz and an S 11 < −10 dB bandwidth ranging from 4-8.6 GHz. The antenna is very simple, composed of an L-slot and a microstrip feedline placed beneath and to the edge of the L-slot. The size of the antenna is 20 × 20 mm 2 which is attractive for compact wireless devices that operate in C-band. The antenna has very low cost and does not require: a large size, truncated corners, reflecting surfaces, complex feeding structure, and via connections, which increase fabrication cost and design complexity.
