This paper describes the design of 8 elements Uniform Circular Antenna Array (UCA) of rectangular patch working at 5 GHz. All the antennas are placed equidistantly in a circular manner with a radius of $0.6lambda_{0}$. By providing appropriate phase shifts between adjacent elements, the UCA can generate multiple OAM beams such as $l= pm 1, pm 2, pm 3$. All these modes are mutually orthogonal to each other and thus can be multiplexed together on the same frequency, i.e., 5GHz. The impedance bandwidth of 200 MHz is obtained by the simulation. The maximum gain of 11.9 dBi is obtained at first order OAM. However, the gain of 9.3 dBi and 8.7 dBi are obtained at second and third order OAM beams, respectively. The proposed antenna array can be used in Wi-Fi applications.

The pro-posed array is achieved using two orthogonal radiating dipole antennas employing the standard ±45° slant technique. The elementary antenna is implemented by two 45° tilted modified dipole antennas printed orthogonal to each other on the top plate of substrate. The other dipole arm is implemented using the middle plate of SICL feeding network. The polarization of the antenna is controlled by exciting the antenna through either of the two feeding ports. A 1×4 stacked array of proposed antenna using L-bent SICL feeding network is utilized to obtain a gain of 7.6 dBi while maintaining good isolation. The proposed antenna resonates at 26 GHz exhibiting wide impedance bandwidth for the two polarization and co-pol to cross-pol ratio better than 23 dB. SICL helps in achieving a compact design by eliminating balun to feed the two arms of the dipole. Moreover, the feed network is compact and attains good isolation due to shielding. Another advantage of designing the antenna in SICL technology is the improvement in front-to-back ratio caused by the reflection of back radiations from the ground plates of SICL feeding network. This antenna finds its utility in n258-NR (New Radio) 5G spectrum endfire applications centered around 26 GHz.","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":"130061545","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}

SAR systems already have their working modes expanded by using dual-band dual-polarized (DBDP) antennas. The shared-aperture design has been used in many configurations to reduce the size of these antennas. This work presents an innovative Dual-band Dual-Polarized Aperture Antenna (DBDP), which operates on a single layer circuit board at X- and Ku-bands. The operating frequency of X band is 9.3 GHz and operating frequency of Ku band is 13.265 GHz. To utilize the common aperture, 5-elements (4-groups) planar array with square microstrip patches are utilized for both Xband and for Ku-band 5-elements (1-group) microstrip patch antenna is used. The proposed design is to enhance the gain and isolation by using series-fed center-fed network. The interelement spacing between two patches is considered $0.7lambda$ for the ±25° scan range requirements. The impedance matching bandwidth is 147/266 MHz (X/Ku), Return loss is −19/− 22.24 dB (X/Ku) and high isolation is 66.9 dB. The size of the antenna is $160 text{mm}times 160 text{mm} times 0.8 text{mm}$ using RT/Duriod 5880 substrate with permittivity 2.2 and the height is 0.8 mm (31 mil).
