Popis:	A design procedure is described which enables simultaneous control of the input‐impedance match, directivity, and bandwidth of segmented antennas. Their impedance properties can be accurately determined by a straightforward multiport analysis, which makes it possible to optimise the values of individual reactances with the use of closed‐form objective functions. Two practical omnidirectional segmented monopole antennas have been designed, built, and tested, to verify the proposed design procedure. One is a single‐tuned design with the narrow bandwidth of 1% and realised gain of 6.7 dBi, and another is the double‐tuned design with 42% relative bandwidth and realised gain of 6.2 dBi.
