The antenna is composed of four arc printed dipoles, a small circular patch, four tapered microstrip transmission lines and four pairs of parasitic strips. To verify the performance of the antenna, simulations and measurements are carried out and discussed. The measured results show that the proposed antenna exhibits a 10-dB impedance bandwidth of 59.3% (2.23- 4.11 GHz). With an omnidirectional radiation pattern in E-plane, the proposed antenna has a peak gain of around 2 dBi across the operational band. The low profile and compact design, along with omnidirectional radiation pattern, make it ideal for wireless applications operated within WLAN (2.4- 2.484 GHz) and WiMAX (2.3GHz, 2.5GHz and 3.5GHz) frequency bands.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133124932","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 whole PA circuit is composed of three stages of amplifier MMICs followed by four microstrip stub resonant cells loaded with film resistors as low Q-fator resonators. Traditionally, the resonator cells used for a microwave amplitude equalizer are straight short or open stubs. In order to fulfill the shaping of amplitude curve over a nearly quadruple frequency band, we propose a circuit scheme where microstrip step-impedance resonators (SIR) loaded with thin-film resistors are utilized to increase the degree of freedom in the design of the amplitude-shaping circuit. The return loss and insertion loss of the amplitude-shaping circuit is optimized by Ansoft HFSS to fit the pre-specified curve in frequency domain. A prototype of the amplitude-shaped PA is designed and fabricated. The measured results of frequency response of the output power are in agreement with the specified one with a difference less than ±1.0dB within 5-19GHz. Experimental results indicate that the proposed low Q-factor resonant cells consisting of the SIRs and thin-film resistors are well suited for the design of ultra-wideband amplitude equalizing and shaping circuits.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133886556","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}

In some typical TWR scenarios, electromagnetic wave propagates through two layers with different physical properties parameters. Traditional methods for the time-delay calculation in such situations are usually using three-dimensional searching algorithm or solving three variables equation of four times and tedious and time-wasting. This paper presents a new fast time-delay algorithm for electromagnetic wave propagating through two layers. An equation of two lateral distances through the walls can be established because of the fact that incident angle at upside of the walls equals to refracting angle at the downside of the walls. Total propagation path and time delay can be calculated by the two lateral distances subsequently. Simulating experiments prove the new algorithm is suitable for real-time time-delay calculation in TWR signal processing.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114457671","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}
