“…The simulated result for a 400μm radius radial resonator is shown in Figure-10. The radial resonator was first reported in 1993 by Simons [9] who also used double stub radial resonator [10] to enhance the Q factor however this occupied a lot o f ch ip area. In pract ical terms it is difficult to calcu late the radius of a radial resonator for a particular resonant frequency.…”

The paper describes the planar Gunn diode, which is well suited to providing milli-metric and tera hertz sources using microwave monolithic integrated circuit (MMIC) technologies. Different planar Gunn electrode geometries are described along with DC, RF and thermal characterisation. To realize the planar high frequency sources there is requirement for high frequency planar resonators, the paper will describe both the radial and new diamond shaped geometries.

“…Microwave integrated resonators are widely used in microwave and milli‐metric components, which include filters , oscillators , and antennas . One form of the integrated resonator is the coplanar waveguide (cpw) radial resonator and more recently the diamond resonator which has been shown to occupy 55% less chip area than a comparable radial stub resonator .…”

A novel method of introducing a notch at a point of high magnetic field in a coplanar waveguide (cpw) radial and diamond stub resonator to increase the quality factor (Q) was analyzed. For comparison, both radial‐ and diamond‐shaped cpw resonators with and without notches were fabricated on gallium arsenide (GaAs) semi‐insulating substrate at the James Watt Nanofabrication Centre and tested in the milli‐metric laboratory at University of Glasgow. The notch increased the loaded Q factor of the diamond resonator by approximately 28% and good agreement was obtained between the measured and simulated loaded Q for both cpw radial and diamond resonators. © 2015 Wiley Periodicals, Inc.

“…In addition, the use of uniplanar technology circumvents the need for via holes to connect the center conductor to ground. However, while the subject of resonators is now very mature, there is relatively little literature on coplanar waveguide (CPW) resonators [9]- [11].…”

A class of novel millimetric uniplanar series resonators are presented, which can be used in monolithic and hybrid uniplanar microwave integrated circuits (MIC's). The proposed structures are able to demonstrate low radiation and compactness characteristics, which are attractive for passive and active monolithic and hybrid integrated circuits. A principle of achieving these high-quality circuits is described and also confirmed by experimental and theoretical results, which are in good agreement up to 50 GHz. To illustrate the features of the proposed series resonators and demonstrate their effectiveness, two classes of miniature coplanar waveguide (CPW) filters (namely, lowpass and bandpass) are designed using these resonators. The developed low-pass filter has some important advantages such as low insertion loss in passband, very wide stopband, high cutoff rates, small size, low number of elements, and an effective control of spurious signals. On the other hand, the newly developed bandpass filter provides an alternative, yet compact, structure to classical filters. Obviously, many other classes of filters or passive components can also be designed.
