We show a design with a single vertical beam of gain 25 dBi that could support the simultaneous transmission of power to three rotary winged SUAV. It would be powered by a 5 kW UHF (915 MHz) magnetron-based generator. We also show a design producing a conical beam of gain 18 dBi that would allow multiple conventionally winged, electrically propelled to fly in a circular path around the antenna, at altitudes of 10-30 m, whilst dipping a wing into the beam. The wing would contain a rectenna, or an array of rectennas, depending on mission requirements and SUAV design, and receive 15 W per rectenna at 10 m assuming a 30 kW transmitter.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125792645","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}

A LC-matching circuit is used to have the antenna resonance in VHF band. In order to have a compact structure a device is used to switch between the two bands (UHF and VHF). Experimental and numerical results demonstrate that the proposed antenna exhibits a bandwidth of approximately 12.3% and 4% for UHF (420 MHz) and VHF (167 MHz) respectively. The total efficiency of the antenna was measured with two methods (reverberation chamber and Wheeler cap): it was higher than 90% in the both UHF and VHF bands. A switch device was introduced to have one antenna, and good results were obtained. Gain measurement is performed in UHF band.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128954735","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}

At the lower bands of the LTE systems, designers of mobile handsets antennas face challenges of the conflicting requirements of limited space and long wavelengths. A multi-band PIFA antenna that is printed directly on the substrate is proposed for mobile handset applications. A parametric study using the CST Microwave Suite is presented to show the influences of various design parameters. The antenna design was optimized to attain a bandwidth of (0.67 GHz) centered at (2 GHz). The antenna has a compact size of 60×30×1.6mm3, and can be used to serve many LTE bands in the range of (1.7 GHz) to (2.37 GHz).

The radiator configuration is constructed by assembling thin sheets with different relative permittivities as a stack for generating different effective permittivities for the wave components. It is demonstrated that by using sufficient high inclusion permittivity material together with material close to air, the AAS is observed to show AR <; 2 dB with 25 dBi higher RHCP gain than LHCP. The proposed radiator configuration provides excellent polarization purity in addition to opportunity to be integrated close to other electrical RF components in transceiver to avoid strong wiring losses at mmWaves.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130568831","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}

Antenna design has been one of the key limiting constraints to the development of small communication terminals and also in meeting next generation and radar requirements. Multiple antenna technologies (MATs) have gained much attention in the last few years because of the huge gain. MATs can enhance the reliability and the channel capacity levels. Furthermore, multiple antenna systems can have a big contribution to reduce the interference both in the uplink and the downlink. To increase the communication systems reliability, multiple antennas can be installed at the transmitter or/and at the receiver. The idea behind multiple antenna diversity is to supply the receiver by multiple versions of the same signal transmitted via independent channels. In modern communication transceiver and radar systems, primary aims are to direct high power RF signal from transmitter to antenna while preventing leakage of that large signal into more sensitive frontend of receiver. So, a Single-Pole Double-Throw (SPDT) Transmitter/Receiver (T/R) Switch plays an important role. In this paper, design of smart distributed subarray MIMO (DS-MIMO) microstrip antenna system with controller unit and frequency agile has been introduced and investigated. All the entire proposed antenna system has been evaluated using a commercial software. The final proposed design has been fabricated and the radiation characteristics have been illustrated using network analyzer to meet the requirements for communication and radar applications.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131948012","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}
