“…An amplifier gain of 11 dB at 8.25 GHz with a 3-dB bandwidth of 0.65 GHz was measured. The design concept was confirmed by extensive numerical simulations [36], and development of a -band PDQ power combiner is currently being pursued. Meanwhile, an alternative TE-type PDQ power combiner using printed dipole antennas was also designed [37].…”

Active integrated antennas (AIA's) provide a new paradigm for designing modern microwave and millimeter-wave architecture with desirable features such as compactness, light weight, low cost, low profile, minimum power consumption, and multiple functionality. This paper reviews recent research and development related to this emerging technology with emphasis on its applications in high-efficiency radio-frequency (RF) front-end, millimeter-wave power combining, beam steering, and retrodirective arrays, as well as wireless sensors. Optical controlling techniques for AIA's are also described.

“…This kind of wave launcher was first used for a transition from CPW to substrate integrated image guide [6] and is described there in more detail. Comparable TM 0 slab mode launchers were published by other authors [7,8]. However, the presented design is superior in terms of low parasitic radiation, achievable bandwidth of over 20 %, and almost perfect front-to-back ratio due to the reflector-like back-short vias.…”

A novel type of integrated dielectric antenna is presented, which is suitable for low-loss integrated transceiver front-ends in the upper microwave or millimeter wave frequency ranges. The proposed antenna comprises a dielectric high permittivity substrate acting as grounded slab waveguide and a simple planar lens on top for beam focusing. The guided wave is gradually transformed to free space by a curved ground plane for end-fire radiation from the substrate edge. Apart from high radiation efficiency due to very low conductor losses, the use of a standard substrate material also simplifies manufacturing and allows accommodating MMICs or bias circuitry at minimum cost. Simulation and measurement results are presented for a scaled prototype in X-band. Simulation studies were also conducted at millimeter-wave frequencies, where the low-loss advantage is even more evident. Having dimensions of 10 mm × 18 mm, an example design provides a gain of 15 dBi at 60 GHz and a radiation efficiency of more than 80 % if a Duroid ® 6010LM substrate is used. Good input impedance matching is achieved in a bandwidth of over 20 %, covering the entire unlicensed 60-GHz band.

The Yagi–Uda antenna is one of the most practical and commonly used antennas. It features high gain and low weight and profile, and is inexpensive to manufacture. In this article, the fundamental operation of the Yagi–Uda is discussed, as well as a classic graphical technique for obtaining a fixed gain design. Several modern versions of the Yagi–Uda antenna are also described that permit operation of the antenna at microwave frequencies and allow for simple integration into planar arrays.
