In: Proceedings of the 2014 IEEE Radio and Wireless Symposium. 19-23 Jan 2014, Newport Beach, CA, USA: 100-102.900096119000258690009854http://hdl.handle.net/10454/10833NoA miniaturized conical helix antenna is presented, which displays vertical polarization with electrically small dimensions of 10mm×10mm×45mm. The resonance of the antenna is made tunable by adding a variable digital MEMS capacitor load at the bottom of the helix, giving a tuning range of 316 MHz to 400 MHz. The antenna demonstrates considerable impedance matching bandwidth and gain over the entire tuning frequency band. Most importantly, the antenna is capable of compact, flexible and easy integration into a wireless device package or for platform installation.Helical antennasTuningAntenna radiation patternsCapacitorsLoaded antennasMicromechanical devicesVertical polarisationElectrically small antennaESAOmni-directional antennaTunable antennaConference paperhttps://doi.org/10.1109/RWS.2014.6830109
