Intended antenna is operating well over 1.80-1.83 GHz and 3.37-3.51 GHz with - 10 dB bandwidth of 30 MHz and 140 MHz, respectively. The novelty of this work is to find miniaturized structure by means of meandered ground plane. The electrical size of the proposed antenna is 0.15 λ0 × 0.15 λ0 × 0.009λ0 at the lowest frequency, which confirms its ultra-compact nature. Proposed antenna exhibits maximum radiation in the end-fire direction in first band although monopolar pattern in second band. It also shows minimum cross polarization level at 90° for both of the bands. Simulated gain of 0.16 dBi and 2.05 dBi is observed at 1.82 GHz and 3.45 GHz respectively. Aforementioned results depict that proposed antenna is potentially suitable for 4G (LTE), WiMAX, WLAN/Wi-Fi Applications.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"65 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":"133766922","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 WiFi, bluetooth and Zigbee applications share the 2.4 GHz spectrum of the Industrial, Scientific and Medical (ISM) radio band. The antenna is designed on Rogers RT 5880 (lossy) substrate (2.2, 0.0009) and the height of the substrate is 0.79 mm with an area of 38 x 36 mm2. It provides maximum gain of 2.82 dB and directivity of 2.87 dBi. It yields a good reflection coefficient of -42.17 dB and VSWR of 1.0157 at the resonant frequency of 2.544 GHz. The average radiation efficiency of the array antenna is quite high which is around 92% and it has never gone below 88% within the operating frequency band.

A shorting pin and two L-shaped slots on the radiating patch are used to reduce the electrical size of the antenna. In order to enable circular polarization, four open ended stubs are added to the four corners of the radiating patch. Furthermore, two corners of the ground plane are truncated to enhance the circular polarization purity. A PEC shielding mechanism is placed around the periphery of the antenna to improve the gain and axial ratio performance. The proposed implantable antenna is simulated and optimized using CST Microwave Studio inside a skin box at 3 mm depth. The proposed implantable antenna demonstrates satisfactory performance in terms of impedance bandwidth, axial ratio and embedded gain performance.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"13 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":"114465953","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}

Reducing the RCS of a radar antenna is the primary goal in attaining stealth performance. A compact band-pass FSS (BPFSS) and the circuit analogue absorber with element size 0.27λX0.27λ is designed at the operating frequency band of dipole antenna (10 GHz) to allow the incoming electromagnetic (EM) wave to pass through it to avoid the reflection. Next, a compact wideband absorber is employed to avoid unwanted reflection from the background. The simulations are performed using the commercial full-wave solver and the results are analyzed. The results are promising and encouraging towards the development of such configuration for modern stealth applications.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"3 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":"114886140","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}
