We report a new planar antenna design in the shape of a diamond. The performance of the antenna design is initially obtained through simulation, then fabricated, and its performance evaluated through experiment. Experimental characterization of the diamond‐shaped monopole antenna shows good agreement with simulation. In comparison with a simple monopole antenna, our diamond‐shaped monopole antenna features smaller geometric footprint and displays a higher bandwidth at millimeteric wave frequencies.

f_{0} = - 3 {\times 10}^{- 6} L_{1}^{5} + 5 {\times 10}^{- 4} L_{1}^{4} - 0.0337 L_{1}^{3} + 1.0827 L_{1}^{2} - 17.29 L_{1} + 115.89

“…Whilst using the simulation tool it was found that the choice of mesh size was particularly important in order to obtain a realistic return loss of the dipole antenna especially at higher frequencies [6]. Initial simulation results show that the dipole antennas are resonant at 5.6 GHz with a bandwidth of ~ 1.2 GHz.…”

Understanding the impact of interference upon the performance of a multiple input multiple output (MIMO) based device is of paramount importance in ensuring a design is both resilient and robust. In this work the effect of element-element interference in the creation of multiple channels of a wireless link approaching the near-field regime is studied. The elements of the 2-antenna transmit-and receive-arrays are chosen to be identical folded dipole antennas operating at 5.6 GHz. We find that two equally strong channels can be created even if the antennas interact at sub-wavelength distances, thus confirming previous theoretical predictions.

“…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 . An important parameter of any resonator is its “quality factor” Q , which determines its frequency response .…”

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.
