In this book, an important principle in mobile phone antennas is described. An equivalent circuit representation of the antenna element, the coupled PCB "chassis" and the coupling between them were analyzed. The investigation of the coupling was by 2 port measurements of the two radiators in the antenna-chassis combination. The chassis was tested as a dipole antenna by cutting two arms from the middle at different angles. Several types of balun transformers were used to measure the (chassis-) dipole experimentally. The antenna element was mounted on the (chassis-)dipole to investigate the...
