Leaky-wave antenna (LWA) based on planar waveguide technology (substrate integrated waveguide) is designed using periodic loading of a new type of rectangular slot combination that is capable of beam scanning angle enhancement through broadside. This proposed compact leaky-wave antenna shows high impedance bandwidth of 37% and directive beam scanning in the leaky (fast) wave region (n = −;1) over the frequency band of 8.84 GHz to 12.9 GHz. The open stopband (OSB) problem is eliminated by combining four T-shape slots and rotating at +45° and −45° with respect to the longitudinal axis of the antenna for getting a better impedance matching. The scanning beam position changes from −74° to +15° while the frequency sweep from 8.84 GHz to 12.9 GHz, the return loss of the antenna is seen to be below −;10 dB for the complete frequency band, with a minimum value of −;50 dB. The characteristics of the designed prototype in the form of scattering parameters, radiation pattern, and gain are given.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114671263","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 radiating ring aperture is backed by a cavity that is fed by an aperture coupled microstrip line. H-shaped slots are used for coupling the microstrip line to the cavity due to their small size compared to a simple rectangular slot. Tapered gradient has been used in the H- shaped slots to increase the bandwidth and reduce the cross polar level. The proposed antenna uses a single radiating surface for dual band operation which makes the antenna low profile. A dual port slot coupled arrangement for both the bands poses several challenges thus a tightly packed arrangement of vias around the central aperture is used to improve the coupling between the two bands. The bandwidth achieved at K and Ka band are, 18.06% and 13.9% respectively, minimum element gain across the bands is 6.73 dBi and 5.15 dBi, minimum cross polarization levels are 26.9 dB and 32 dB with a small element of size $9times 9$ mm. The proposed antenna can be used as an element of an array for satcom application.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116985017","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}

To estimate the DoA a goniopolarimetric technique using 3 orthogonal dipole(tri-dipole) antennas are implemented.

The frequency tuning is achieved by using four pin diodes which are placed at appropriate positions on the parasitic rectangular loop. By switching the diodes (ON/OFF) three bands from 2.7 - 3.1 GHz, 3 - 3.5 GHz and 3.5 - 4.5 GHz are obtained. The simulation is carried out in CST Microwave studio and analysis of the antenna is done using parametric study and surface current distribution.

For the purpose genetic algorithm (GA) based optimization technique has been used, with a motive to generate new amplitude values for synthesising the radiation pattern. For optimization purpose in this work a novel cost function has been established in order to get the desired SLL. The newly generated amplitude obtained based on the proposed cost function has been put into the array factor formula in order to get the new array radiation pattern.
