The Bal-Cal kit is a connectivity & calibration kit for VNA-measurements in sub-miniature RF-electronic circuits. You will need the BalCal kit for: - connecting to sub-miniature RF-electronic circuits through UFL-connectors - connecting and measuring in a true balanced way, into lecher-lines - calibrating with UFL-connectors into 50 ohm - calibrating with balanced circuits (lecher-lines), into 50, 10 and 200 ohm The kit comes in a handy accessory box.

http://www.antenna-theory.com presents the analysis of the IFA (inverted-f antenna)! Particularly, the geometry, and fundamental parameters are discussed. The IFA is described in terms of a dipole and a slot antenna. The bandwidth, polarization and impedance are discussed. For more information, see http://www.antenna-theory.com/antennas/aperture/ifa.php
The typical faults marked with XXI and XXII in the other graphs are not visible on first view. If you have a closer look you can detect the peak at 1500 MHz range. The bandwidth of this antenna covers all the four GSM bands, UMTS 2100 and even the 2400 MHz band for Wi-Fi, Bluetooth [...]
