“…Four wearable antennas for on-body applications monitored skin at 2 mm, obesity at 5 mm, muscle at 20 mm and bone at 13 mm. When being examined in the human body, the energy values were 1,620 W/m 3 , 300 W/m 3 , 480 W/m 3 , and 610 W/m 3 , respectively [32]. A triangular microstrip antenna using rectangular grooving technique for use in the 2.38 GHz frequency range was compatible with 2×2 units electromagnetic frequency band plates.…”

This article presents the design of a dipole antenna structure in combination with a square electromagnetic band gap (EBG) to monitor the children trapped in cars using a 750 MHz frequency band which responds the most to human movement detection. The antenna structure was designed on a copper plate with a thickness of 0.297 mm and polyester mylar film baseplate with a thickness of 0.3 mm and dielectric value of 3.2. By design, the dipole antenna had a size of 201.56 × 12.5 mm 2 and 18 × 5 units square electromagnetic band gap (EBG) of size 254.64 × 71.86 mm 2 . The results of the measurement showed that the bandwidth impedance in the operating frequency range was 4.78% (735-771 MHz) with a gain of 6.3 dBi. There was an omnidirectional signal transmission. The dipole antenna had the best distance between the EBG plates of 30 mm. When being examined at a distance of 500-1,600 mm, it was the most effective at an average signal strength of approximately 0.032 mW every time there was movement of a human body in the car.

“…The Capacitive loading, Inductive loading are used in this feeding line meandered technology. The objectives including there are certain frequency ranges that we have to make our cell phones operate and that frequency range have to be covered with designed radiation pattern and proper gain and also constraints are given on this is how antenna design research is focussed in terms of cell phone perspective [1][2][3]. Figure 4 shows the current distribution and 3D radiation pattern of a planar inverted F antenna (Motorola T193 and planar monopole antenna iPhone 4 but the engineering changes depending on the current situation and challenges [6].…”

Antenna means for radiating radio waves, Generally the type of antenna that are used in cell phone handsets in the form of Sleeve dipoles, Whip antennas. In the sleeve dipoles we have a coaxial transmission line, dielectric insert, metal sleeve and line braid. The balancing mode can be achievable with metal sleeve also the stability of the radiation pattern. The role of the dielectric and sleeve are not only maintaining the radiation pattern stable but also walk on the matching. Whenever we have the roll over mobile it is used for getting signal as well as receive signal. Capturing of signal is possible when the mobile starts working. The system represents the capturing of omni directional signal through radiation pattern measurements. The coaxial line inner conductor is along the Z- direction, the signal is symmetric along X-Y plane. In this chapter it is proposed to develop an antenna which can be used as low-cost product in various fields. The construction of the whip antenna must be compact. A spring in the whip antenna plays a vital role as small compact antenna systems which is usually implemented for cell phones. The small compact antenna used for transmitting and receiving signals in an omni-directional system. From the cell phone perspective technology, the printed technology made a significant role which helps in use meandered monopoles used in MEMS. In historical perspective, this complicated design has to concentrate on the types of frequency ranges covered with radiation pattern also we cannot estimate current in the antenna since it is an integrated device, the placement of the other things like a battery also carries power and we have to look into the arrangements in a design in such a way that we must estimate the power dissipation throughout the antenna circuit, we have to rectify if the current which flows through the conductor carries any additional effects. The overall structure of the mobile also affects the radiation pattern. The parasitic effects, nearby circuits, placement of the other devices in a mobile affects the electromagnetic energy distribution. Similarly in all the fields the antenna can be developed with low-cost product manufacturing.

“…Two ellipticalshaped Concentric Complimentary SRR slots are introduced in the patch for tri-band notch characteristics those frequencies are 3.3 to 3.7 GHz WiMAX, 3.8 to 4.2 GHz downlink C-band and 5.2 to 5.8 GHz in WLAN. A novel Meta structure wearable antenna is introduced by Ramanpreet et al [18] for WBAN devices and is integrated with two designs. The microstrip patch is introduced in the upper layer and the lower layer shape is a Meta structure.…”

The antenna plays an essential role in the medical industry. The shortrange 5 th Generation (5G) communication can be used for seamless transmission, reception, patient monitoring, sensing and measuring various processes at high speeds. A passive Ultra Wide Band (UWB) antenna, used as a sensor in the measurement of Prothrombin Time (PT) i.e., blood clot is being proposed. The investigated micro-strip patch UWB antenna operating in the frequency range of 3.1 to 10.6 GHz consists of a circular patch with a diamond-shaped slot made of jeans substrate material with good sensing properties is accomplished by adjusting the copper thickness of the patch. Due to the turbidity in blood plasma, PT measurement is the repetitive approach to get accurate value. In order to solve this issue, an antenna is designed, fabricated and analysed to obtain the accurate PT measurements from blood plasma. The blood clotting is observed by electromagnetic emitted voltage converted into the frequency range of 5 to 10 GHz and voltage range of 0.66 to 0.87 mV. The circular UWB antenna is constructed employing jean's substrate with a partial ground plane to improve the S-parameter, gain, bandwidth and performance characteristics. The proposed antenna with Specific Absorption Rate (SAR) value within the acceptable range can be used as a wearable device in the human body, leveraging 5G technology. This antenna is well suited for various other applications like wireless sensors, wearable devices and short-range communication applications.
