“…According to (Kumar et al, 2017), the CP antenna offers steering flexibility between the transmitter and receiver in addition to mitigating the effects of multipath fading. Widely used navigation systems such as BeiDou Navigation Satellite System (BDS), Galileo, Global Positioning System (GPS), Global Navigation Satellite System, and Quasi-Zenith Satellite System use L-band right-handed circular polarization (RHCP) antennas for their operation (Babakhani et al, 2017). The L band (1-2 GHz) is divided into five sub-bands: L1 (1575.42 MHz), L2 (1227.6 MHz), L3 (1381.05 MHz), L4 (1379.913 MHz) and L5 (1176.45 MHz) for various operations of GPS (Mishra et al, 2020).…”

Günümüzde mikroşerit antenler, yüksek performans gerektiren araçlarda, uçaklarda, askeri uçaklarda, İnsansız Hava Araçlarında (İHA), uzay araçlarında, radar sistemlerinde, uydu ve füze uygulamaları gibi pek çok havacılık alanında tercih edilmektedirler. Bu çalışmada, Mikro şerit yama antenlerin havacılık sektöründe kullanım alanları ve özellikle küresel konumlama sistemlerinde (GPS- Global Positioning System) kullanımı araştırılmış ve GPS L5 güvenlik bandında örnek bir mikroşerit yama anten tasarımı gerçekleştirilmiştir. Tasarımı gerçekleştirilen yüksek kazançlı ve dairesel polarizasyonlu anten High Frequency Structural Simulator (HFSS) program ile simüle edilerek sonuçlar incelenmiştir. Yapılan simülasyonların nümerik analizinde neticesinde 1176 MHz merkez frekansında, S11 değerinin -38.85 dB olan, band genişliğinin 54 MHz ve kazancının ise 6.07 dBm olduğu görülmüştür. Elde edilen bu değerler neticesinde küresel konum belirleme L5 güvenlik bandında kullanılabileceği sonucuna varılmıştır.

“…CP antennas can reduce multipath fading effects and improve the flexibility in orientation of transmitting and receiving terminals [1, 2]. Some of the widely used navigation systems such as Global Positioning System (GPS), GLONASS, Galileo, Bei Dou Navigation Satellite System (BDS), and Navigation with Indian Constellation (NavIC) make use of L -band (1–2 GHz) antennas with right-hand circular polarization (RHCP) [3, 4]. Based on the type of system, the L -band is further divided into many sub-bands: L5 (1176.45 MHz), L2 (1227.6 MHz), L4 (1379.913 MHz), L3 (1381.05 MHz), and L1 (1575.42 MHz) with ±2% bandwidth requirement.…”

The paper presents a new coplanar waveguide (CPW)-fed rectangular patch antenna with a square-shaped ground plane that can be employed in modern advanced navigation systems. For realizing broad impedance bandwidth in the proposed antenna, a wide slot is introduced in the square ground plane and the rectangular patch is shifted toward the left edge of the ground surface. In addition, by means of introducing square-shaped stubs near the left and right edge of the ground plane, the circular polarization is achieved at L1, L2, and L5 satellite bands. As per the simulation results, the proposed antenna provides a wide impedance bandwidth (S11<−10 dB) of 123% (1.12–4.72 GHz) and 3 dB axial ratio bandwidth of 11% (1.15–1.29 GHz) and 18% (1.5–1.8 GHz) suitable for multipurpose wireless applications. The designed single feed circularly polarized antenna is low profile, small size, light weight and easily integrable with other high-frequency communication devices. To validate radiation performance of the proposed structure, the antenna is fabricated and integrated with the commercially available Global Positioning System (GPS) receiver and it is found that the measured values are in close agreement with the desired results.

In this paper, a circularly polarized (CP) planar antenna covering global positioning system (GPS) L1 (1575.42 MHz), L2 (1227.6 MHz), and L5 (1176.45 MHz) bands is presented. The antenna consists of an elliptical patch excited through the inset feed line. A pair of concentric ring slots is etched on the ground plane to achieve dual‐band response that covers L5/L2 and L1 bands. The circular polarization is achieved by integrating a quarter‐wavelength arc with the inset feed and loading a pair of slits on the elliptical patch. In addition, the quarter‐wavelength arc improves the impedance bandwidth of the lower resonant band to cover the GPS L5 band. The antenna shows right‐hand circular polarization (RHCP) in all the three bands. The antenna also satisfies the ±1 dBi gain flatness criteria of the GPS antenna. A prototype antenna is fabricated and experimental results are found in a good match with the simulated results.
