The antenna, with dimensions of 12 mm × 11.6 mm × 0.508 mm (1.036λo ×1.001λo×0.043λo where λo is computed at lowest cutoff frequency), is fabricated on a Rogers RT/duroid 5880 (tm) substrate with a relative permittivity of 2.2 and a dielectric loss tangent of 0.0009. The suggested antenna consists of four U-shaped radiating elements (patches) on top of the dielectric material and a slotted ground on the bottom. The radiating elements are fed by a 50-ohm microstrip line feed. To improve the impedance performance of the MIMO antenna, a rectangular strip of 1.3 mm × 0.2 mm and a couple of rectangular slots are added to each radiating element. The first operating band at 27.1 GHz, ranging from 25.9 GHz to 27.8 GHz, is achieved by using slotted U-shaped radiating elements. The second operating band at 48.7 GHz, ranging from 47....

The paper postulates a compact microstrip circular ring antenna operating at three different bands. The designed antenna is appropriate for Wi-Max, C-band, and wireless LAN applications. An FR4 substrate of thickness 1.6 mm is considered upon which a circular ring monopole antenna is developed. The truncated or reduced ground plane is considered in the design of the proposed antenna to yield the desired resonant characteristics. The developed antenna resonates at various multiband frequencies of 2.55-3.6, 4.37-5.32, and 6.99-8.65 GHz with good gain characteristics. The simulated reflection coefficient values are less than -10 dB. The proposed antenna has higher gains at all the three bands. A prototype of the proposed antenna is fabricated, and measured results are compared to simulated results with good matching in between them.

A novel offset feed mechanism is adopted to obtain directional behavior from a conventional planar structure. The proposed antenna is designed on a Silicon-dioxide (SiO 2) dielectric substrate having a permittivity (ε r) of 4 and a height of 60µm. A gold material of thickness 5µm is used as a conducting metal in the top and bottom layers. This antenna consists of an offset feed patch, partial ground as a reflector, and three director elements forming a Quasi-Yagi antenna. This conformal structure operates from 270 GHz to 333 GHz and provides a peak gain of 8.62dBi at 300 GHz in the end-fire direction. An analysis of different metals and parametric variation in metal thickness, substrate thickness, patch length, and width is also reported for a better understanding of the evolution of the proposed structure. A lumped equivalent circuit is also developed for the proposed structure to study its transmission line model. A good agreement is also noted between the EM simulation (HFSS, CST) and circuit simulation (ADS).
