Frequency switchable active antenna

TL;DR: This paper proposes a novel Active Antenna that has capability of frequency switching and the passive antenna with rectangular slot and frequency splitter is used to design the proposed AA.
Abstract: This paper proposes a novel Active Antenna (AA) has capability of frequency switching. The passive antenna with rectangular slot and frequency splitter is used to design the proposed AA. Two separate networks are designed at two separate frequencies and integrated with three port rectangular slot antenna. PIN Diode switches are used to switch between two networks for achieving frequency switching. The proposed antenna can be used for WLAN applications.

TL;DR: In this article, an FET source was integrated with a microstrip patch antenna to form an active radiating module, which served both as a radiating element and a resonator in the feedback loop for the FET oscillator.
Abstract: An FET source has been integrated with a microstrip patch antenna to form an active radiating module. The patch antenna serves both as a radiating element and a resonator in the feedback loop for the FET oscillator. Power output of 17mW was achieved at 5.7 GHz.

TL;DR: In this paper, a dual-port dual-band annular slot antenna was designed for use in the feed-back path of an oscillator resulting in an active antenna configuration.
Abstract: This report presents the design of a dual-port dual-band annular slot antenna suitable for use in the feed-back path of an oscillator resulting in an active antenna configuration. The proposed antenna is designed to radiate and transmit equal amounts of power. The return loss of the proposed antenna is higher than that desired for one-port antenna application at the desired dual-band frequencies. The antenna is fabricated on one side of a Neltec substrate (e r =3.2 and thickness = 0.762 mm) and the microstrip feeding line is fabricated on the opposite side of the board. The antenna was designed to operate at WLAN bands centered at 2.4 and 5.2 GHz. The simulated and measured results show fairly good agreement. The measured return losses were found 20.5 dB at 2.4 GHz and 13.9 dB at 5.2GHz while simulated return losses were 9.36 dB at 2.4 GHz and 31.35 dB at 5.2 GHz. The radiation pattern is approximately omnidirectional at both frequencies in H-plane.
