As was briefly mentioned in section 1.7, 'wire' antennas are analysed through the radiating properties of r.f. currents on wires. The simplest wire antenna is the dipole, shown in figure 2.1(a). It is usually easier to derive the radiating properties of antennas when transmitting, and then...

A design technique for wire antennas, based on the Structure-Based Evolutionary Programming, is used to design a broadband antenna with an end-fire radiation pattern and a very simple geometry, operating in the 3???16???GHz frequency band, namely, from the S band to the Ku band. The ...
The results show a minimum return loss of 14.24 dB and a gain of 0.22 dBi at 33.8 GHz. The radiation efficiency of the antenna is 74%, which is considerably higher than standard on-chip antennas. 展开 关键词: CMOS integrated circuits antenna radiation patterns finite element analysis impedance...
