“…On the other hand, amplifying active antennas reported in [15][16][17][18][19] showed improved power added efficiency (PAE). The physical significance relies in the fact that the antenna inherently acts as a bandstop structure which suppresses the higher order harmonics and provides higher efficiency.…”

A co‐design methodology for antenna miniaturisation with an integrated radio frequency (RF) amplifier is proposed for power‐efficient and compact RF front‐ends. This approach relaxes the standalone antenna matching requirement which is of interest in miniaturised antenna design. The detailed design and measurement procedure is presented and the concept is demonstrated with two examples for both narrowband and wideband scenarios considering transmitting and receiving front‐ends. The amplifiers and the antennas are co‐designed so that optimum performance is achieved in terms of gain, noise figure and efficiency. The antenna has the size of 0.033λ02 at 2.45 GHz. It is miniaturised from its natural resonance frequency of 3.5–2.45 GHz which provides 51% of size reduction. The minimum bandwidth of the integrated antenna is found to be 37 and 150 MHz, respectively, for the narrowband and wideband designs. The active integrated antenna (AIA) efficiency is more than 47% when operating in the band of 2.45–2.6 GHz. The gain and noise figure of the AIA systems are optimised along with the antenna performance and found to be >10 dB and <2 dB, respectively. Measurement results are presented which are in well agreement with the design procedure and simulations.

“…Efforts have been done in integrating the amplifier in the antenna [1] resulting in an increase of both, the effective gain of the antenna and the figure of merit (G/T). From a circuit point of view the integration of a mixer in the antenna will yield to a more compact and simpler receiver or transmitter design [2].…”
