A portable coaxial collinear antenna
IEEE Transactions on Antennas and Propagation, 1972A novel collinear antenna constructed of coaxial cable with inner- and outer-conductors interchanged at half-wavelength intervals is described. A 26-element antenna of this type has been constructed and evaluated. Design criteria presented allow extension to the use of coaxial cable of different types in a variety of radio/radar arrays.

The coaxial collinear antenna: Current distribution from the cylindrical antenna equation
IEEE Transactions on Antennas and Propagation, 1987A theoretical model and computer simulations of the current on the coaxial collinear (COCO) antenna are presented. Comparisons between numerical results and measurements are made for 24- and 26-element COCO antennas at 50 MHz and for six- and eight-element COCO antennas at 915 MHz.

Design of a Wideband Coaxial Collinear Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019This paper presents a wideband high-gain coaxial collinear antenna with a stable radiation pattern. Based on the fat dipole idea, the configuration of the classical coaxial collinear antenna is modified and an 8-section coaxial collinear antenna is designed. The -10dB impedance bandwidth of the proposed antenna reaches 36.5 MHz at a center frequency of

Amelioration of Coaxial Cavity Antenna
2020 IEEE 3rd International Conference on Electronics Technology (ICET), 2020In order to improve the impedance bandwidth of the antenna, a method of amelioration is proposed. An improved scheme of the coaxial feed antenna is proposed. The influences of its configuration parameters upon its impedance bandwidth are simulated. The impendence wide band of the single feed can increase to two-octave and it can gain up to 3dB.
