Ground effects on arc-shaped conformal dielectric resonator antennas (DRAs) working in the TE z 11δ mode are investigated and utilized to attain various radiation performances. Manipulation of directivity patterns are achieved with the help of the three-dimensional curved metal ground. The backlobe, beamwidth, broadside gain, backscattering, and cross-polarization level of the antenna are all readily controllable. The geometric theory of diffraction is applied to provide an intuitional explanation for the radiation changes. Detailed analysis is then conducted from the perspective of ground current. It is found that the current distribution is affected by configurations of both the arc DRA and ground plane. Based on this, analytical methods are developed to calculate the ground effects exclusively for conformal arc-shaped DRAs. Next, the design theory of arc DRAs with curved ground is proposed. To demonstrate it, two conformal DRAs owning directional and wide beams, respectively, are designed as paradigms. At last, a prototype is fabricated and measured for validation.

“…In the past years, increasing interest of wireless communications at microwave unlicensed frequency band [1,67], especially at 60 GHz due to high capacity of wireless networks in the wireless personal area network (WPAN) has urged the need for new antennas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Specifically, its WPAN application on multi-gbps wireless connectivity for short range communications between electronic devices with 40-100 times data rates compared to current WLAN technologies can be realized.…”

A mm-wave circularly polarized (CP) fractal antenna has been designed and simulated using standard 0.18 urn CMOS with six metal-layer structure. The proposed design consists of a wideband circularly polarized multi-segment circular fractal antenna with circular polarization at the top layer M6. The proposed CFA has a small size of 25×25× and operates over the frequency band between 49.8-and 64.5-GHz with < . The multi segment circular fractal structure is employed for antenna design because the circular segments can excites two orthogonal vectors current to achieve circular polarized radiation. The proposed CMOS antenna can offer a simulated peak gain of -1.71 dBi and a simulated axial ratio bandwidth to cover over operating band from 50 to 64.5 GHz.Index Terms-antenna, CMOS, mm-wave, 60 GHz, and Fractal.I.

Compact arc-shaped conformal dielectric resonator antennas (DRAs) loaded by metal plates and high-dielectric-constant (HiK) patches are investigated. Their miniaturizing principles are analyzed from different aspects. Closed-form expressions are derived to characterize the function of the conformal ground in size reduction. Difference between the conventional flat ground and conformal one is discussed. As to lateral metal loading, its influence on radiation patterns are utilized to acquire additional function. Next, to replace the metallic structure, HiK patches are used as perfect electric conductor (PEC) walls. Their working mechanisms are analyzed through the electromagnetic theory in layered media, and waveguidebased simulation methods. As validation, a dielectric-loaded arc DRA is proposed. By working like a PEC, the thin dielectric patch reduces the DRA size to one half. Similar characteristics are observed between the dielectric-and metal-loaded antennas. Finally, a bare DRA and a miniaturized one are fabricated and measured. This research expands the miniaturizing theory of conformal arc DRAs.INDEX TERMS Compact antennas, conformal antennas, dielectric resonator antennas, dense dielectric patches, radiation patterns.
