The resulting set is a high efficiency transmitting active antenna. The dimensions, shape and location of the feeding point in the antenna are selected to obtain an input impedance to force the transistor to work in class “E” at 885 MHz with very high collector efficiency: ηc=90%@Vcc=12.5, Pout=1.5 W High efficiency mode “E” amplifier powers high efficiency active transmitting patch antenna Ortega Asensio Gonzalez Jimenez Martin doi:10.1109/MWSYM.1998.705031 Microwave Symposium Digest, 1998 IEEE MTT-S International, Vol. 2 (1998), pp. 455-458 vol.2. 2008-05-09T07:26:00-00:00 1998 Microwave Symposium Digest, 1998 IEEE MTT-S International 2 455 458 vol.2 active amplifier antenna efficiency high patch transmitter http://www.citeulike.org/user/dcastro/article/2774600 <i>Infrared and Millimeter Waves, 2002.

Experimental results show that an increase of power in the fundamental oscillator frequency can be also observed. Several advanced structures are presented for optimal rejection of the undesired harmonics.
