“…Several effective approaches have been developed to achieve compact size for GPS/BDS antennas in the past two decades [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]. Existing compact BDS/GPS antennas include ceramic patches [1,2,3,4], shorting probe loading antennas [5,6], slot-loaded patch and quadruple inverted-F antenna (QIFA) [7,8,9], leading to antennas as small as 0 =9.…”

“…Among the compact circular polarization (CP) antennas, ring patch antennas have received considerable attention because of their physically smaller size as compared to patch antennas [10,11,12,13,14,15,16,17,18,19,20,21]. In [10], a compact meandered ring patch antenna loaded with four parasitic-grounded patches and a slotted ground is proposed while its overall size is 0:285 g Â 0:285 g Â 0:035 g , more compact than the square-ring designs in [11,12].…”

A novel compact active BeiDou helical antenna, operating at normal mode is proposed for high-shock projectile applications. To achieve excellent impedance matching, a grounded matching stub is introduced in this design. For demonstration, a prototype with extremely compact size (22 × 22 mm) is fabricated and measured. The measured reflection coefficients below 10-dB is almost 15 MHz centered at 1268 MHz. Omni-directional radiation pattern of the proposed antenna is realized. Additionally, stable signal reception under various motion attitudes could also be proved by experiments.

“…By using the low temperature co‐fired ceramic (LTCC), the CP antenna with two patches stacked without air gap or foam layer has obtained a good performance . Due to the broadband phase shifter and Wilkinson power combiners, a concentric annular‐ring microstrip antenna fed by four apertures has achieved a improved ARBW . A dual‐coupled shorting probe (DCSP)‐loaded patch antenna for dual‐band GPS application is presented in Ref.…”

This letter presents the design of a broadband microstrip CP antenna using single‐fed technique. The feeding network is integrated within the coupling feed patch to simplify the structure. The proposed antenna is designed for Global Navigation satellite System (GNSS) operating at 1575.42 ± 10.23 MHz (GPS: L1 band), 1559∼1592 MHz (Galileo: E2‐L1‐E1 band), 1602 ± 5.625 MHz (GLONASS: L1 band) and 1559.052∼1591.788 MHz & 1610∼1626.5 MHz (BeiDou Navigation Satellite System B1 and L band). Another advantage of this antenna is the much wider bandwidth in both VSWR and 3 dB axial‐ratio compared with traditional single‐fed CP antennas. Details of design, simulated and experimental results of this CP antenna are presented and discussed. The measured results confirm the validity of this design which meet the requirement of GNSS applications.

“…The antenna is designed by using different feeding techniques such as coplanar feed-line [12], L-probe proximity fed annular ring microstrip antennas [13] and electromagnetically coupled microstrip antenna with V-slots and notches for broadband operation have been proposed in [14] and its bandwidth up to 51% with gain 7 dBi. One of the most popular techniques is the use of a multilayer structure consisting of several parasitic patch antenna structure appeared in [15,16] the literature on bandwidth enhancement of microstrip antenna. Further, compact and wide band microstrip antenna has been widely reported with different technologies such as slotted patch antenna with defected ground structure [17], loading with fractal resonator [18], multi-frequency monopole antennas by loading metamaterial transmission line and magneto-electrodielectric planar waveguide metamaterial [19,20].…”
