| Popis: | In this paper, we discuss the impedance and radiation properties of planar UWB (any ultra wide frequency band) dual-polarized antennas. While their performance is usually de¯ned using the impedance bandwidth, some applications require pattern stability over broad frequency bands. An analysis of the behaviour of three UWB dual-polarized antennas (Bowtie Antenna, Toothed Log- Periodic Antenna and Sinuous Antenna) showed interesting conclusions in terms of impedance matching bandwidth and radiation pattern steadiness. Starting from there, we then developped a method that consists in meandering the original structure. This method allows for miniaturization as well as radiation bandwidth enhancement. As a ¯nal result, an electrically small antenna with an impedance bandwidth of more than a decade and a steady radiation pattern over it has been developped. |
