“…Various active integrated antennas based on different configuration of the antenna or different combination of the radiator element with amplifiers, mixers, and oscillators have been presented in the literature [6][7][8][9][10][11][12][13][14][15][16]. Moreover, some of them have been proposed as transmitter-receiver (transceiver) units [17]. The key issue in the design of the active integrated transceivers is that the isolation between the transmitter and receiver ports must be maintained.…”

Abstract-A new design of dual-port monopole-slot-like microstrip active integrated antenna (AIA) is presented and discussed in this paper. The primary designed passive antenna is capable of supporting two different WLAN bands at 2.4-2.84 GHz and 5.15-5.35 GHz due to its dual-port structure. In order to reduce the transmission coefficient between the two ports of antenna a coupling sleeve-arm and an inverted T-shaped slot are utilized on the ground plane of antenna each beneath one of the corresponding feed-lines which act as filtering structures at desirable frequencies. The proposed passive dual-port antenna is integrated with a power amplifier (PA) and a low noise amplifier forming a dualport microstrip AIA which can be used as a full-duplex transceiver at its operating WLAN frequency bands. The measured results for both passive and active antennas show that the designed antennas have proper radiation characteristics at their desired operation frequencies. The fabricated passive antenna exhibits dual-band performance at 2-3.42 GHz and 4.5-5.6 GHz while the fabricated AIA covers 2.31-2.82 GHz (at PA port) and 4.45-5.5 GHz (at LNA Port) with 13 dB and 9 dB gain level improvement respectively.

“…The distinct advantages of the circular polarization antenna over the linear polarization antennas are the flexibility of the transmitter and the receiver orientations [5][6][7]. Numerous researches have been done in microstrip planar antennas with circular polarizations and switchable circular polarizations by integrating active components [8]. Furthermore, new concepts and technologies keep emerging in the wireless communications systems.…”

Abstract-In this paper, a technical concept and design of circular polarization detection patch array antenna using a double-balanced RF multiplier is proposed. The microwave integration technology is effectively employed to realize the proposed array antenna. The double-balanced RF multiplier is integrated with an orthogonal planar array antenna. The array antenna which consists of 12 patch elements and the RF multiplier is realized by embedding four zero bias Schottky barrier diodes on a slot-ring. The Both-sided MIC technology is successfully employed to realize the array antenna. The array antenna is realized in a very simple and compact structure as all the antenna elements, feeding circuit and the RF multiplier are integrated on both sides of a dielectric substrate. The ability of the proposed array antenna to detect the orthogonal circular polarization (LHCP and RHCP) is successfully confirmed by the experimental investigation.

“…Such low carrier mobility limits the operating frequency of the organic or polymer based flexible electronics circuit to a few kHz [4]. The low operating frequency makes this kind of electronics unsuitable for active PAA applications, where multi-GHz operating frequency is required for different communication bands [5][6][7][8][9].…”

We present a flexible active 2-bit 2-element phased-array antenna (PAA) fully fabricated using ink-jet printing technology. High speed carbon nanotube (CNT) based field effect transistors (FETs) function as switch in the true-time delay line of the PAA. The 2-bit 2-element active PAA is printed out at room temperature on 100μm thick Kapton substrate. The FET switch works well for 5GHz RF signals. An ON-OFF ratio of over 100 is obtained at a low Vds bias of 1.8V. The measured azimuth beamsteering angles of PAA agree well with simulation values.
