By properly adjusting the input admittance of the matching network, each channel of the diplexer can be designed independently. The diplexer can be easily realized by the connection of different bandpass filters without further tuning. The matching network is comprised by some open- and short-circuited transmission lines, and source-load coupling can also be conveniently introduced. Moreover, the proposed matching network occupies little place, and thus the size of the diplexer is mostly determined by the filters. To illustrate the concept, a diplexer has been designed, fabricated and measured. Simulated and measured results are found to be in good agreement with each other.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129772020","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 MEMS switches were symmetrically loaded in the microstrip antenna. By controlling the states of the switches, the surface current distribution will be changed and then the operating frequency will be widened. For further broadening the bandwidth and increasing the gain, the antenna was designed as a meander-line structure by using the fractal method. After using software HFSS to simulate, the results show that the reconfigurable microstrip antenna can work at L, C and X band, the gain is more than 4. 85dB with good radiation characteristics.

In MIMO beamforming transmitter, a couple of radio frequency (RF) channels are paralleled to transmit signals simultaneously, it is almost impractical to perform linearization for each channel individually. The proposed method can not only achieve good linearization effect, but also greatly simplifies the system structure. A simple MIMO system with 2×4 beamformer is constructed to evaluate the proposed method. The experiment is based on two Long Term Evolution (LTE) signals with different bandwidth and peak-to-average power ratio (PAPR) operating at 2.12 GHz and 2.18 GHz, respectively. With a two dimensional memory polynomials (2-D-MP) model, the nonlinearity of the transmitter is compensated, and the adjacent channels power ratio (ACPR) can reach lower than -45dBc, which has been compressed 9-21 dB in the results.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121416963","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}
