The working frequencies of the A-shaped, N-shaped and T-shaped antenna are 2.28 GHz, 2.22 GHz and 2.10 GHz, respectively. For the ANT-shaped antenna which is formed by a combination of the three letters antennas, the radiation performance and the mutual coupling of the antenna are analyzed. It can be seen that the radiation characteristics of the letter-shaped antennas are similar to the normal patch antennas. The Letter-shaped and word-shaped antennas have prominent advantage in stealthy and embellished antennas.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123563481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By replacing the series capacitors used in the conventional CL CPW ZOR antenna with varactor diodes and properly designing the feed-in capacitor, a well-matched and continuously tunable resonant frequency is acquired. For a satisfactory rf-dc isolation without using bias Tee, a simple dc bias circuit for the varactor diodes is devised. For verification, the proposed antenna is designed, fabricated, and tested, and its performance is compared to other frequencytunable ZOR antennas. Limited by the capacitance tuning range of the varactor diodes at hand, the operating frequency of the prototype antenna is tunable only from 2.54 GHz to 2.78 GHz as the dc bias voltage is changed from 0 to 10 V. Nonetheless, the proposed design has a simple planar structure and a compact size while exhibiting a reasonable gain in between 1.23 and 2.03 dBi.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129314324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed radiated element consists of three split rings,i.e., the feeding ring, the main radiated ring, and the parasitic ring. In virtue of hybrid magnetic-electric coupling between the three split rings, a wide frequency band (2.2 GHz - 4.7 GHz), compact size (50 mm $times50.7$ mm) can be achieved by a single antenna. After that, a MIMO antenna consisting of four radiators is constructed and the distance between the nearest elements is only 5 mm. The minimum electrical length is λ0 (λ0 is the wavelength of the lowest resonance).

MWI suffers from low spatial resolution for accurate diagnosis, while MTAI is unable to provide quantitative dielectric information and its image quality degrades due to acoustic heterogeneity of breast tissue. To compensate for these drawbacks, we propose a microwave-based dual imaging modality, by combining the conventional MWI and MTAI, for breast tumor detection. First, a low-resolution MWI image will be utilized to provide a rough estimate of the high-dielectric region in breast. Then, the high-dielectric region will be incorporated in MTAI reconstruction to mitigate the acoustic heterogeneity effect. Finally, medical images with ultrasonic resolution and quantitative dielectric information of breast tissue can be ob- tained. We verified this idea by imaging anatomically realistic numerical breast phantoms. Simulation results demonstrate the feasibility of the proposed dual imaging modality by significantly improving the image fidelity and providing quantitative dielectric information.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121318274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
