“…However, the operating frequency of this kind of antenna is relatively low, which makes it difficult to improve and does not accord with the frequently used image transmission frequencies at 2.4 GHz and 5.8 GHz. In [3], a compact CP patch antenna with a wide AR beam width operating at dual bands compatible for GPS satellite navigation applications is proposed, [18] obtained a dual-band dual-polarized omnidirectional antenna loaded with eight open slots and eight shorted metal pins, and a dual-band antenna using ZOR and FOR mentioned above is realized in [4]. Although these operating frequencies of antennas have more applications, the working BW of the antennas is still narrow, and unable to meet practical demands.…”

A dual-band omnidirectional circularly polarized (CP) antenna using composite right/lefthanded (CRLH) transmission line (TL) with miniaturized size is presented. The antenna consists of a circular radiation patch and a circular ground connected by three copper shorting vias, on which three rectangular slits are etched. Two sets of opposite branches are arranged in sequence around the radiation patch and ground to widen the impedance bandwidth (BW). The zeroth-order resonance (ZOR) structure by CRLH-TL and meandering technology allow miniaturization of the antenna, and rectangular slits realize wide low axialratio (AR) performance in the azimuth plane. The dual-band antenna is fabricated and measured. The overall size of the antenna prototype is only 0.208 × 0.208 × 0.026 , where is the free-space wavelength at the center working frequency of the low band. The BW in the lower band has a range of 2.39 GHz to 2.42 GHz, equivalent to 1.25%, and that of the upper band has a range of 5.6 GHz to 6.0 GHz, equivalent to 6.90%. The AR bandwidth (ARBW) has ranges of 1.9 GHz to 2.6 GHz at 2.4 GHz, approximately 29.2%, and 4.6 GHz to 7.3 GHz at 5.8 GHz, equivalent to 46.6%. The overlap BW covers the two frequencies of unmanned aerial vehicle (UAV) image transmission, 2.4 GHz and 5.8 GHz in China.

“…In the item of impedance bandwidth and 3 dB AR bandwidth, the proposed antenna shows better performance than the antennas in [9,11,14]. However, compared with [10][11][12][13], the proposed antenna has smaller volume and lower profile. In summary, the proposed antenna features the characteristics of wider bandwidth and HPBWs with compact dimension and low profile.…”

A low-profile dual-band circular polarized (CP) patch antenna with wide half-power beamwidths (HPBWs) is presented for CNSS applications. Simple stacked circular patches are used to achieve dual-band radiation. To enhance the HPBW for the two operation bands, a dual annular parasitic metal strip (D-APMS) combined with reduced ground plane (R-GP) is presented. A single-input feed network based on the coupled line transdirectional (CL-TRD) coupler is also proposed to provide two orthogonal modes at the two frequency bands simultaneously. Experimental results show that the 10 dB impedance bandwidth is 32.7%. The 3 dB axial ratio (AR) bandwidths for the lower and upper bands are 4.1% and 6.5%, respectively. At 1.207 GHz, the antenna has the HPBW of 123° and 103° in the xoz and yoz planes, separately. And the values are 127° and 113° at 1.561 GHz.

This paper proposes a compact dual-band printed quadrifilar helix antenna (QHA) operating at GPS-L1 (1575 ± 2 MHz) and L2 (1228 ± 2 MHz) bands. To generate the dual operating bands, two interconnected lines with unequal lengths are introduced as a radiating element. The closely allocated radiators resonate in quarter-wavelength mode, which significantly miniaturizes antenna's size. Four shunt capacitors are loaded near ports to manipulate the mutual coupling between each two radiators, so that satisfactory matching condition with minimum active reflection at two target bands can be obtained simultaneously. Then, a compact feeding network consisting of on-chip hybrid couplers is designed and connected to the QHA. Measured results show that the compact proposed antenna achieves peak gains of 1.5 dBic and 2.6 dBic at 1575 MHz and 1228 MHz, respectively. The axial ratios (ARs) at L1 and L2 bands are both below 2.5 dB, and the half-power-beamwidths (HPBWs) are as wide as 130 and 116 , respectively. As compared with reported works, the proposed antenna can achieve much more compact size (0.11 × 0.21 λ 0 2) and dual-band radiation at the same time.
