Patch antennas loaded with different resonator elements
MetadataShow full item record
Nowadays, the tuning in the bandwidth and frequency is present in all the different devices and applications that we are using in our daily life. The development of 4G LTE networks and Wi-Fi are driving a dramatic increase in the number of radio frequency (RF) bands that smartphones and other mobile devices must support. For that, in this research, different designs are studied, simulated and measured in order to observe a possible tunable response that an antenna can obtain when it is loaded with resonator elements. First all, the basic patch antenna on FR-4 is studied working at different ...
