A loop-type ground antenna formed by connecting a capacitor between two ground points is described. The resonant frequency of the ground loop is conveniently controlled by changing the capacitance. The proposed loop-type radiator is excited by conventional shorting line loop feeding that may include an inductor. A loop type ground antenna is designed for Bluetooth and Wi-Fi applications.
An LC-loaded folded monopole antenna including two meander-line inductors and an interdigitated capacitor was designed for a miniaturization of antenna. The operating frequency of the antenna was essentially determined by the resonant characteristics of the uniquely arranged distributed inductors and capacitor, not by the length of the radiator, so that the size of the antenna can be designed to be...
UMTS antenna duplexers for handsets require high levels of wide-band rejection while still achieving high isolation, low insertion loss, and good return loss in-band. Several of the UMTS duplexers also require very steep filter skirts due to a very small guardband between transmit (Tx) and receive (Rx) frequency bands (Bands 2 and 8 have ~1% guardband). Without sizeable inductors to stretch the bandwidth,...
