“…Although high gain can be achieved in Reference , narrow operating bandwidth and large frequency ratio ( f H / f L ) are the main disadvantages of this design. In Reference , the use of ME‐dipole has been demonstrated to exhibit wide operating bandwidth and high gain as well; however, it suffers from larger frequency ratio and significantly higher profile in comparison with our approach of using crossed dipoles.…”

“…In recent years, electric dipoles in crossed configuration have been widely used to design dual‐band or multiband CP antennas . Compared to the ME dipole, the use of crossed dipoles to realize CP radiation is more convenient and less complicated structure as well. However, there still exist several disadvantages for the designs in References .…”

This paper presents a new approach to design dual‐band antenna with dual‐sense circularly polarized (CP) operation. A principle for CP radiation is the use of two orthogonal dipoles and properly choosing their lengths can produce either right‐hand CP (RHCP) or left‐hand CP (LHCP) operation. In the proposed structure, the lower frequency band at 2.4 GHz is designed with RHCP radiation and LHCP is the operating mode of the higher band at 3.5 GHz. For verification, an antenna prototype is fabricated and measured. Measured data indicate that good performances over the RHCP and LHCP bands can be obtained with usable bandwidths of 2.9% (2.36‐2.43 GHz) and 1.7% (3.48‐3.54 GHz). Along with this, it also observes good unidirectional radiation patterns and the measured broadside gains are around 7.7 and 7.4 dBic across these frequency ranges.

“…Printed dipole antennas with two L‐slotted or U‐slotted arms for dual‐band operation are proposed in Refs 3 and 4. Recently, metamaterial‐loaded antenna, slot antenna, and magneto‐electric dipole antennas have been also studied. However, the out‐of‐band radiation characteristics of these reported antennas have been rarely concerned.…”

A printed dual‐band dipole filtenna with flexible frequency ratio and improved band‐notched performance is proposed. It consists of a driven dipole and three parasitic elements. For the driven dipole with short and long arms, a radiation null is found between two passbands, which achieves a band‐notched filtering characteristic. Two parasitic elements are introduced to enhance the passband bandwidth and an additional parasitic element is utilized to improve the band‐notched performance. In addition, the characteristics of the proposed design including flexible frequency ratio, independent controllable operating frequency, and controllable band‐notched bandwidth have also been demonstrated. A filtenna prototype is fabricated and tested. Measured results show that a fractional bandwidth of 21.1% and 18.1% is obtained in the lower and upper passbands, respectively. The measured efficiency is 84% in the lower band and 74% in the upper band but the efficiency sharply decreases to about 13% within the notched band.

A compact dual band cross dipole antenna surrounded with metallic plates at five sides has been proposed in this article. comparative analysis has been done between the dipole and cross dipole antenna. On comparing these two antennas the proposed antenna has the high gain of 7db and radiation efficiency of 95 percent. The peak directivity of the proposed antenna is 5DB and its front to back ration is 60. The return loss, gain, radiation patterns and co polarization and cross polarization of the antenna has been observed and analysed using AN-soft HFSS v13.The proposed antenna works at the range of 0.6GHz to 1.5GHz which covers the applications like GSM, GNSS and some of the applications which covers in the range of UHF and VHF.
