“…Some methods can be used to alleviate this uneasiness. One of them is to hide the antenna in some practical covers like car window [19], rear view mirror [20] and chimney [21], but it has the drawback that the covers would more or less interfere with the normal operation of the antenna. Another method is to use the artistic antenna, such as swan DRA [22], apple DRA [22] and Chinese-character patch antennas [23]- [25].…”

Design of the wide dual-band rectangular souvenir dielectric resonator antenna (DRA) is discussed. The proposed wide dual-band rectangular DRA was excited by using a U-slot. The TE 111 y mode of the rectangular DRA and the slot resonator were employed to design the lower band, while the higher-order TE 113 y and TE 311 y modes were utilized to design the upper band. By merging two pairs of modes in each band, the impedance bandwidth of the lower and upper bands were enhanced simultaneously. New design formulas that determine the dimensions of the wide dual-band rectangular DRA were obtained. Design guideline was also given to facilitate the design. To demonstrate the usefulness of the formulas, a wide dual-band rectangular DRA fabricated using K-9 glass was designed for 2.4/5.2-GHz WLAN applications. To upgrade the antenna as the souvenir-DRA, the word ''LOVE'' was carved on the sidewall of the glass DRA by using the sandblasting machine, and it was found that the content and position of the word has little effect on the antenna performance. The impedance bandwidths of the proposed wide dual-band DRA can be achieved as ∼25% for the lower band and ∼13% for the upper band. INDEX TERMS Rectangular souvenir dielectric resonator antenna, wide dual-band.

“…In such environments, large antenna to antenna separation provides larger probability of signal distribution with a better chance of either one of the antenna picking up the desired signal. This idea was used in (Yegin, 2013) by placing antennas in the exterior rear-view mirrors of a vehicle and a very good reception quality was reported. However, the system implementation requires retooling and designing rear-view mirrors, thus is of higher cost compared with on-glass antenna placement.…”

To cite this article: Korkut Yeğin (2015) On-glass automotive diversity antenna and LNA design for S-band satellite digital radioSelection combining diversity system with antennas mounted on windshield and backlite of a vehicle is proposed for satellite digital audio radio applications. Standalone exterior mount antennas on metallic vehicles perform well for satellite digital audio radio applications, but for composite body vehicles or interior mount antennas, antenna performance becomes a real issue. Proposed on-glass two-antenna diversity is one solution for such applications. The antenna correlation is calculated using the S-parameters of the antennas and found to be very low due to many wavelengths separation between the antennas. Design of low noise amplifier, which has sub 1 dB noise figure and good P1dB due to strong cellular signals, is also detailed. A diversity receiver is described and ride tests are performed to assess the performance of the diversity system in real-time, under weak satellite signal environment which is regarded as the most challenging reception condition.

Design of High-Gain Circularly Polarized Antennas Based on Vehicle Application Environment

et al. 2020

In this paper, a novel circularly polarized (CP) antenna that achieves high gain by maximizing the radiation aperture utilization is proposed for vehicle applications. The realization of increasing the radiation aperture is based on the application environment, making full utilization of the vehicle roof, a large metal reflector beneath the antenna, which is indispensable in the vehicle application. Developed from the structure of typical microstrip patch antenna, the design extends the radiation patch to cover the side of the dielectric substrate, which increases the size of the radiating patch without increasing the antenna's outline size. To make CP antennas more suitable for special working environments with large reflecting surface, a sequential rotation feeding structure with 90 • progressive phase difference is uniquely designed based on the active port impedance of the four-ended radiation structure. This co-design method introduces the active port impedance of a multi-port radiator into the design of feeding network as the loads can effectively guarantee the CP performance of the antenna, and can greatly simplify the optimization work in the subsequent stage. Based on this design idea, a prototype working at 1.48 GHz with a 50-MHz bandwidth is designed for vehicle satellite broadcasting application. Experimental results show that the antenna achieves a high CP gain greater than 7 dBic with a compact size of 50 × 50 × 10mm 3 (0.247λ 0 × 0.247λ 0 × 0.05λ 0 , λ 0 is the wavelength of working frequency in free space). INDEX TERMS Vehicle satellite broadcasting, high gain, circular polarization, sequential rotation feeding, extreme radiation aperture.
