Item type:Publication, Compact flat monopole antenna for small aircraft of VHF communication system(2012-11-26); Kawdungta, S.This paper presents the design of compact flat monopole antenna for the small aircraft of VHF communication system. It can operate along the wide frequency band without the matching circuit that make itself compact size. From the simulation results, the proposed antenna has a frequency range between 112 and 130 MHz. It yields an omnidirectional pattern with a linear polarization. The simulated gain is 1.88 dBi. The prototype antenna was fabricated and tested with the VHF aircraft communication system. It has sufficient characteristics for the VHF communication system. It is found that this antenna can be efficiently used for the small aircraft. © 2012 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A parasitic printed monopole antenna for a VHF mobile communication(2012-11-26); Kawdungta, SupakitIn this paper, the parasitic printed monopole antenna is proposed for the VHF mobile communication. The parasitic monopole is added with the printed monopole to achieve a good impedance matching and desired gain. The simulated results show a good matching at the operating frequency. The obtained antenna gain is around 2 dBi with the omnidirectional radiation pattern. The prototype antenna was fabricated and tested to verify the theoretical predictions. It is apparent that this antenna can be a potential candidate for the VHF communication system. © 2012 IEEE.
