“…Fig (11). Radiation pattern of CCSR-SCS Antenna at 10.1GHz Further Current distribution of proposed antenna at different frequencies of 2.47 GHz, 3.44 GHz, 3.99 GHz, 5.5 GHz, 8.1 GHz and 10.1 GHz are shown in Fig (12), Fig (13), Fig (14), Fig (15), Fig( 16) and Fig( 17) respectively. Current is much stronger around the edges of the CCSR-SCS antenna along with uniform distribution of current over entire patch indicating that patch size plays important role at lower frequencies and current distribution for upper bands is mainly from the split ring as strong current distribution moves towards the center of the patch.…”

“…Mobile telephony systems for example, allow portable devices compliant with GSM900/DCS1800/ UMTS2000 technologies and the same devices will also link users to WLAN networks based on 802.11 standards (2.4/3.6/4.9/5/5.9GHz) specifications. Hence, it is of great interest to develop patch antenna with multiple resonances [4][5][6][7].Many researchers have made huge efforts to design slot/slit based antennas on the radiating patch and ground plane, which can be used for multiband operations [8][9][10][11][12][13][14].Reconfigurable antennas are still attracting many researchers for designing multiband antennas [15][16][17].Metamaterials are the promising new candidates for designing multiband antennas [18][19][20].Fractals have been investigated for multiband antenna operations [21,22].Stacking of antennas for multiband operation has also been investigated [23,24].…”

Circular polarization reconfigurable antenna for mid-band 5G applications with a new reconfigurable technique

“…Polarization reconfigurable antenna (PRA) is a multifunction antenna which has the ability to modify its polarization states at different time by using switches [1,2]. In this type, the reconfigurability can be done among horizontal polarization (HP), vertical polarization (VP), polarization with a specific angle, left-hand circular polarization (LHCP), and right-hand circular polarization (RHCP) [3,4]. Among all these types, Circular Polarization (CP) reconfigurable antennas have been received much attention due to many interesting advantages.…”
