A novel compact broadband Canonical Sleeve Antenna (CSA) covering 500-3600 MHz with omni directional characteristics is presented in this paper. A new method is employed in which the radiating antenna structure is designed as combination of three different canonical structures: hemispherical, conical and cylindrical elements. To accomplish the broad bandwidth with compact size, dipole antenna is designed by using cylindrical sleeve over the hemispherical dipole with conical extensions and cylindrical attachments. Performance characteristics of CSA is simulated and compared with BiConical Antenna (BCA) and other antenna configurations and found to be best antenna configuration with compact form factor. The antenna has height of 111.43 mm and diameter of 116.66 mm. Simulation studies are carried out using CST Microwave Studio. The simulated results are validated by fabricating CSA and evaluating its performance metrics. CSA has 7.2:1 bandwidth with measured VSWR <2.7:1 and Gain varies from 0 to 3.6 dBi. The antenna finds use in wireless communication industry, spectrum monitoring and defence applications.

“…Comparing with the center-feeding scheme, the offset-feeding can bring more flexibility for wideband impedance matching, especially in the low frequency band [9]. In [9], with an offset rate of 34%, a thick dipole (length/diameter = 7.5) was successfully designed and developed, which achieved an impedance bandwidth of more than 10 : 1. Based on this idea, a printed offset-feeding/asymmetrical dipole is presented in this letter.…”

Abstract-The proposed dipole antenna consists of two printed strips with unequal lengths and is fed by a coplanar strip (CPS) line. As the antenna parameters and port impedance are properly selected, a super wide operating band (|S 11 | < −10 dB) of 3.5 to 20.0 GHz is realized. Antenna samples were fabricated using standard PCB process. The area of the constructed dipole antenna is 40.0 × 5.0 mm 2 . The S-parameter measurement was performed via a transition (CPS to double-sided parallel strip line) and transformer (190 to 50 Ohm). The measured fractional bandwidth achieved 139.3% (from 3.4 to 19.0 GHz) as predicted, over which the antenna peak gain is better than 0 dBi.
