The measurement of the radiation and matching performance of millimeter-wave antennas is a very challenging topic. As a single antenna usually has a size of a few square millimeters, the feeding scheme can't be as simple as a connector, especially if high measurement accuracy is needed. That's why a microelectronic probe-feeding technique is a...

Numerous small antennas have been designated at the Electronics, Antennas and Telecommunication Laboratory (LEAT) of the University of Nice Sophia-Antipolis. In this paper, we perform a detailed analysis of the most interesting concepts. We especially focus on the different miniaturization employed to reduce the size of the antennas.

Two novel miniature multiband antennas suitable for mobile phone and WLAN applications have been presented in this paper. The first antenna achieves low return loss and good efficiency in the GSM and the DCS/PCS/UMTS bands while the second structure covers the 5 GHz WLAN bands in addition with same performance.

This letter presents the design of a compact Planar Inverted-F Antenna (PIFA) suitable for cellular telephone applications. The quarter-wavelength antenna combines the use of a slot, shorted parasitic patches and capacitive loads to achieve multiband operation. The commercial electromagnetic software IE3D is used to design and optimize the...
