“…A microstrip patch antenna (MPA) consists of a conducting patch of any planar geometry on one side of a dielectric substrate backed by a ground plane on the other side [2][3][4]20]. Such antennas received considerable attention starting in 1970s [3] and are used now to implement hybrid MIC and MMIC transceiver modules [5].…”

“…Therefore, complete transmitter modules can be implemented in a single substrate. Such modules are of increasing interest, as system designers require more complex functions to be implemented in a reduced space [1][2][3][4][5][6]. The microstrip antennas are low profile, conformable to planar and nonplanar surfaces, simple and inexpensive to manufacture using modern printed-circuit technology, mechanically robust, and compatible with MMIC designs.…”

Abstract-The purpose of this paper is to present a complete design and analysis of a new integrated balanced transmitter operated at 4 GHz using microstrip technology. It comprises a 4 GHz two-port negative resistance oscillator and a microstrip-patch antenna resonated at 4 GHz. Three different modules are designed and analyzed. The first one used a Lange coupler as a power splitter while the second and third used a one (two)-section branch coupler. The components of the three modules are designed using full-scale computer simulation program named with MSDES, performed by the author, which fully takes into account all the discontinuities included in the microstrip lines, while the modules are analyzed and optimized using APLAC V7.61 software. The design methodologies of the two-port negative resistance oscillator and microstrip patch antenna are introduced and explained. The analyses of the designed modules show a better efficiency and good performance. The modules give a transmit-antenna gain of 15.7 dB with antenna beam widths 91.7 • and 18.2 • in Eand H-planes, respectively. The complete schematic diagrams of the transmitter modules are drawn. These modules can be used in satellite communications, Doppler and other radars, active and semi-active seekers, radio altimeters, missile technology, weapon fuzing, manpack equipments, remote sensing, feed elements in complex antennas, satellite navigation receivers, and biomedical radiators.

“…In [14] an AIA with two separate radiating elements for full duplex operation is presented. Each radiating element of the proposed antenna in [18] has its individual amplifier stage and so it can transmit and receive the signal simultaneously. In [19] an integrated active circulator antenna is proposed in which Gunn diodes are used as amplifiers and isolating elements concurrently.…”

“…The key issue in the design of the active integrated transceivers is that the isolation between the transmitter and receiver ports must be maintained. The Isolation can be achieved by an auxiliary circuit, or instead of using an external additional component the isolation between ports can be produced by using the inherent properties of microstrip antennas [18,19]. In [14] an AIA with two separate radiating elements for full duplex operation is presented.…”

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.

Microstrip antenna arrays offer low‐profile solutions to many antenna applications with potentially low cost. Their low profile comes about from the use of microstrip patch radiators fed by microstrip circuit‐based feed networks, or by using the naturally occurring radiation from the feed networks to form a beam. Both patches and microstrip feeds consist of metallic strips or shapes photoetched on one side of a grounded substrate and can be made using conventional photolithographic processes. The use of the microstrip transmission‐line medium, widely used in both hybrid and monolithic radiofrequency circuits, also gives rise to a unique potential for integration with active devices and radio front ends. This article gives an overview of microstrip array architectures. These include parallel‐ and series‐fed arrays and also arrays formed by discontinuities in a microstrip line, such as the serpent and rampart lines. Other forms such as ultrawideband arrays, leaky‐wave arrays, multilayer arrays, sequentially rotated arrays, multibeam arrays, reflect arrays, and active integrated arrays are also described. The article concludes by describing the impact on array design of important factors such as accuracy in pattern synthesis, feed loss and radiation, and mutual coupling.
