Collinear antenna assembly and series-fed omnidirectional collinear antenna array

A series-fed omnidirectional single-band high gain collinear antenna array, comprising:

• a feed-through connector, a supporting tube, an impedance matching assembly and a single-band collinear antenna assembly connected in series;
• wherein an antenna radiating unit at an end portion of the collinear antenna assembly is connected to the impedance matching assembly;
• and
• the single-band collinear antenna assembly comprises:
• a plurality of phase delayers connected in series and interspaced with a plurality of antenna radiating units, wherein an end portion of each phase delayer is connected to one or more antenna radiating units;
• each phase delayer comprises a circuit wire printed on a dielectric plate, a first and second ends of the circuit wire are connected to the one or more antenna radiating units,
• wherein a wire length, a wire width and a wire spacing of the circuit wire of each phase delayer are determined based on preset wiring rules for achieving a high radiation gain of the single-band collinear antenna assembly,
• wherein a first preset wiring rule is applied to a first phase delayer, a second preset wiring rule is applied to a second phase delayer, and at least one of the wire lengths, the wire widths and the wire spacings of the circuit wire of the first phase delayer is different from at least one of the wire lengths, the wire widths and the wire spacings of the circuit wire of the second phase delayer, wherein the first preset wiring rule is different from the second preset wiring rule,
• wherein the preset wiring rules are determined according to a phase and an amplitude fed to each antenna radiating unit,
• wherein the feed-through connector comprises a feeder and a joint and
• a maximum radiation efficiency of each antenna radiating unit is controlled based on the determined preset wiring rules applied to each phase delayer.
