“…They differ by 0.3 dB, which belongs to the uncertainty of the measurement. Related work on single antenna design reports similar peak total efficiencies: −6 dB at 600 MHz in [24], −4 dB at 700 MHz [25], [26], and −2.6 dB at 750 MHz in [27]. It can be noted that the trace loss can be both simulated and measured.…”

With the future long term evolution (LTE) auction for television white spaces at 600 MHz, there is a strong need for efficient handset antennas operating at very low frequencies. This communication shows a tunable antenna covering the LTE bands from 600 MHz to 2.6 GHz. The antenna uses state-of-the-art microelectromechanical system tunable capacitors in order to reconfigure its operating frequency. In this communication, the design mitigates the tuning loss with a tunable extended ground plane. The resulting dual-resonant antenna exhibits a peak total efficiency of −3.9 dB at 600 MHz.

“…This section discusses several reconfigurable antenna solutions that have appeared in industry, as well as the scientific literature [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. The selection criteria included those reconfigurable antenna solutions for multiband behavior at two frequency regions: a first one from 698 MHz to 960 MHz and a second one from 1.71 GHz to at least 2.17 GHz.…”

Wireless devices such as smart meters, trackers, and sensors need connections at multiple frequency bands with low power consumption, thus requiring multiband and efficient antenna systems. At the same time, antennas should be small to easily fit in the scarce space existing in wireless devices. Small, multiband, and efficient operation is addressed here with non-resonant antenna elements, featuring volumes less than 90 mm3 for operating at 698–960 MHz as well as some bands in a higher frequency range of 1710–2690 MHz. These antenna elements are called antenna boosters, since they excite currents on the ground plane of the wireless device and do not rely on shaping complex geometric shapes to obtain multiband behavior, but rather the design of a multiband matching network. This design approach results in a simpler, easier, and faster method than creating a new antenna for every device. Since multiband operation is achieved through a matching network, frequency bands can be configured and optimized with a reconfigurable matching network. Two kinds of reconfigurable multiband architectures with antenna boosters are presented. The first one includes a digitally tunable capacitor, and the second one includes radiofrequency switches. The results show that antenna boosters with reconfigurable architectures feature multiband behavior with very small sizes, compared with other prior-art techniques.
