Design of Antennas for Handheld DVB-H ... - Lunds tekniska högskola

Figure 4.5. PIFA antenna.
The bandwidth of the PIFA is increasing with the height above the ground plane.
Therefore the height of the antenna is the most important parameter for a PIFA to
cover the whole DVB-H band. The total height for the PIFA is 15 mm to get
required bandwidth (see return loss graph in figure 4.6).
Though the purpose is to develop an antenna for handheld devices we decided to
not continue with PIFA because it needs a too large height above ground plane to
fit inside a terminal.
