Inkjet-printed filtennas with triple bandnotch [PDF]
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016 This paper presents the layout and results of a compact inkjet-printed filtenna operating at the S-band, ISM and UWB frequencies. The filtenna has a wide passband and, alongside, rejects WiMAX 3.5 GHz, WLAN 5.8 GHz and ITU service 8.2 GHz bands. The filtenna is simulated, printed using silver nanoparticle ink on flexible Kapton substrate and measured ...

Reconfigurable and Tunable Filtenna for Cognitive LTE Femtocell Base Stations
International Journal of Microwave Science and Technology, Volume 2016, Issue 1, 2016., 2016 A single‐port uniplanar antenna with a built‐in tunable filter is presented for operation in multiple LTE bands for cognitive femtocell applications. The antenna is based on a monopole microstrip patch fed by coplanar waveguide. The frequency reconfigurability is achieved by using two PIN diodes to couple or decouple a ring slot resonator filter from ...
