Abstract :
This paper gives an overview of the techniques published over the past years to address continuous frequency tuning. It presents the challenges that have been encountered and relates to each other the parameters that influence the losses of the resulting antenna structure. A mock-up is made with a PIFA and a packaged RF-MEMS tunable capacitor to measure its efficiency as the resonance is tuned towards the LTE-700 band.
