“…Antennas with more than one radiation and/or impedance characteristic are essential for cooperative use of different technologies in the same network infrastructure. Among the features stand out high gain [4]- [6], wideband [7]- [9] and circularly polarized [10]- [12]. X-band (8.0 GHz to 12 GHz) applications such as marine radars [13], CubeSat satellites [14] and radar systems [15] have driven the development of multifunctional antennas.…”

A hemispherical dielectric lens antenna is proposed to provide beam-steering for communication networks operating in Xband. Two different printed antennas are simultaneously used to guarantee high performance and diversity of applications, one a wideband linear polarized antenna, and the other a narrowband circular polarized antenna. To ensure this, the design relies on adding printed angled feeders correctly positioned in relation to the center of a homogeneous dielectric lens. A prototype was simulated, fabricated and tested. The measured results show that the antenna is capable of operating from 8.0 GHz to 12 GHz (gain of 14.2 dBi) or 9.5 GHz to 10 GHz (gain of 17.52 dBi).

The design of compact unbalanced-/balanced-to-unbalanced diplexer (U2U/B2U) based on full dual-mode dielectric resonator (DR) is investigated for the first time. The relationships of the external quality factors (Q e ) under the two modes are analyzed. It is found that the Q e of two modes can be controlled independently, which makes the design procedure simple and efficient. Based on the analysis, both of the proposed U2U and B2U diplexer can be easily built by properly adding feeding probes for the DR without increasing the circuit size by altering the location of the feeding probes according to the distribution of the electromagnetic fields. To verify the proposed design concept, the diplexers mentioned above are simulated, implemented and measured. The isolation is achieved by the orthogonality between modes while the low insertion loss is obtained due to the high unloaded quality factor (Q u ) of the dual-mode DR. The measurements are in accordance with the simulated results, showing low loss and good selectivity.INDEX TERMS Miniaturization, dual-mode dielectric resonator (DR), diplexer, design approach, unbalanced-to-unbalanced (U2U), balanced-to-unbalanced (B2U).

“…With the help of the travelling current on the S-shaped dipole arm [10], AR bandwidth of 60% is achieved with the wide AR beamwidth. In addition, by using series-feed method [11]- [12] and quadrature feed networks [13]- [15], broadband antennas are achieved for the stable unidirectional CP radiation.…”
