[ANGLÈS] Dielectrics are insulators and they might therefore seem to be unlikely materials out of which to try and make antennas, but if they are excited in the right way they can be made to radiate very efficiently. Taking advantage of the properties of dielectric materials, a Yagi-Uda antenna based on a high-permittivity ceramic material operating at 3.68 GHz is described. The three-element array features a simulated directivity of approximately 8 dBi and a front-to-back ratio of 10.5 dB. Measured impedance match to 50 Ohm microstrip lines is better than -30 dB at the resonance frequency f = 3.68 GHz, exhibiting an input reflection which remains below -10 dB within the impedance bandwidth of about 10% with regard the resonance frequency. ...
