The spacing between the inner edges of the two antennas is only 3mm for a compact size, and the proposed CMLRs are inserted symmetrically at the edge of the antennas. The simulated results illustrate that the port isolation of the antenna is better than 34 dB at resonant frequency (2.6 GHz) with the introduction of the CMLRs under the premise of a good matching. In addition, the radiation patterns of the antenna with CMLRs are significantly improved at 2.6 GHz compared to coupled antennas.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116954362","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}

Because it has many advantages, such as high efficiency, low cross-polarization level and simple structure. However, the traditional planar slot array antennas has some difficulties in Beamforming. For example, the phase distribution of the planar slot array antenna can not be adjusted flexibly. Here, a proactive conformal waveguide slot array antenna is designed with a cosecant squared pattern on its H-plane. It can control the phase distribution by the shape of the antenna. Based on this, the proactive conformal waveguide slot array antenna can modulate the amplitude and phase distribution independently. And it can be applied to realize the cosecant squared pattern. 3-D printing process technology is applied to print the antenna structure as a whole piece.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127114595","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 probe method is used to measure the electromagnetic field inside the plasma. The plasma generator is a confined space, and the metal cavity wall will have a multipath effect on the probe detection signal. Based on that, this paper designs a unidirectional reception and high temperature resistance electric field probe. The probe adopts the method of connecting the microstrip antenna with the inner conductor of the coaxial probe to reduce the influence of multipath effect and make the signal detection result more accurate. Through simulations and experiments, the probe has good gain and good directivity in the 4.8-5GHz frequency band, and the probe significantly suppresses the influence of multipath effects compared to ordinary coaxial probes.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127455775","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}

Four PIN diodes are integrated in each element of the microstrip array antenna. By controlling the on and off of the four diodes at the same time, the microstrip array antenna can exhibit radiation characteristics with reconfigurable frequencies. When diodes are turn off, the operating frequency band of the antenna is 12.1-12.SGHz with the maximum radiation gain of 11.8dB. When the diode is turn on, the operating frequency band of the antenna is 13.1-13.8GHz, the maximum radiation gain is 11.6dB.
