“…Apart from military application, such radars find the wide utilization as reliable and imperceptible sensors in guarding systems [5], anti-collision sensors for transport, for instance, for cars, including radars for observation of latency car zones and their parking in dense rural conditions [2], [3]. In railway transport, they can be used as measuring systems for car motion parameters in hump yards of large railway junctions, in occupation detectors of pointworks and railway crossings [6].…”

“…Recently self mixing Gunn mounted active antennas have been reported [3,4] at L-band for a half duplex communication system and at X-band for transceiver and spatial power combining applications. An active antenna is basically an oscillator and then a radiator, its device characteristic under injection locked condition shows an interesting modification [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In this paper, a detailed comparative study in case of reception of a FM signal between active microstrip patch antenna (AMPA) and active microstrip slotted ring antenna (ASRA) has been discussed.…”

A Gunn mounted active microstrip patch antenna (AMPA) and active microstrip slot antenna (ASRA) has been investigated for the reception of FM microwave signal. Current well/valley phenomenon has been successfully utilized to demodulate the modulation information. Reception poperty of the both antennas are studied in multi-channel environment. Because of its simple circuit configuration and similarity in transmitter and receiver architecture, active patch antenna as demonstrated is well suited for commercial and military application as a two-way microwave communication system. A comparative study on the role of AMPA and ASRA as a receiver shows that ASRA do better performances than AMPA. In case of ASRA the modulating signal are demodulated without any distortion. ASRA also has large locking range (29 MHz) compare to AMPA (5 MHz). So the ASRA has broad band tuning capabilities than AMPA. With ASRA configuration demodulation bandwidth in excess of 14 MHz is realizable which can successfully accommodate a large number of voice or data channels.

An active antenna is an antenna system in which the antenna is an integral part of the circuit supplying the signal to (driving) the antenna, in transmit mode, and/or the circuit receiving the signal from the antenna is an integral part of the antenna, in the receiving mode. Such an antenna system can exhibit characteristics which are quite distinct from those exhibited by an ideal linear antenna which is electrically isolated from its feed, or read‐out, network. The first section of this article gives an historical perspective on developments in radio technology before giving a qualitative discussion of transmission line modes and antenna modes and how these modes need to relate to one and another in an active configuration. The second section of this article is quantitative and first introduces the Poynting vector in order to analyze impedance matching from an electromagnetic viewpoint before presenting a circuit theoretical discussion of oscillators and their impedance matching requirements. The third section of the article discusses some applications such as active impedance matching, parametric down conversion, power boosting, proximity detection, and active retroflection as well as quasi‐optical power combining (borrowing from array concepts introduced in the second section)
