The radiation characteristics of a stacked microstrip antenna geometry proficient of providing circular polarization along with wide impedance bandwidth is simulated by using IE3D software and later on this antenna was fabricated on FR-4 substrate with an air gap and testing is done in free space. The feed location, location of applied shorting pin and width of air gap introduced between driver element and parasitically coupled element were optimized to obtain best results. The measured impedance bandwidth better than 31.72% and axial ratio bandwidth close to 1.68% were achieved with the proposed geometry. The simulated and measured results obtained are in good match with each other.

A design of annular ring microstrip antenna with finite ground structure is proposed in this paper. The proposed geometry offers impedance bandwidth of 2.362 GHz and has stable radiation patterns for all resonant frequencies in the operational band. It is also found that shape and dimension of the finite ground plane is a key factor in improving the bandwidth of the proposed geometry. The geometry is low profile and has simple structure, therefore can be used for lower band of ultra-wideband applications.

A novel design of a circular patch antenna having defected ground structure is presented in this communication. The antenna is designed for C-band applications. A wide bandwidth of 60.3% (4.04–7.28) GHz is obtained in the C-band frequency range 4–8 GHz. It is also found through parametric analysis that shape and dimensions of the finite ground plane and slots in the patch are the key factors in improving the bandwidth of the proposed geometry. The antenna is fabricated using FR-4 substrate and parameters like return loss, VSWR and input impedance are measured experimentally.

This paper presents the design and synthesis of a nature-inspired micro-strip patch antenna based on the sunflower structure. The antenna structure was based on the Fibonacci pattern found in a sunflower, with the antenna elements in the position of the seeds. Simulation is done using computer simulation technology Microwave studio and the geometry offers impedance bandwidth of 5.28 GHz with enhanced radiation parameters. The geometry has simple structure, therefore can be used for satellite communication applications.

The biomedical telemetry provides diagnostic inspection and monitoring of physiological signals at a far distance. Nowadays implanted medical devices are recent advances in this field. Patch antennas are main devices to send these signals at far distance and attain high attention for integration into implantable medical devices. Implantable patch antennas can be designed for transfer of high-speed data rate for transferring high quality video from implanted patch to outside telemetry. Dedicated MICS band (402–405 MHz) is not sufficient enough for transferring the real-time videos. High data rate for transferring real-time videos can be achieved in IEEE 802.11 (2.4 GHz) ISM band (5.725–5.825 and 2.4–2.5 GHz). The objective of this study is to analyze the performance of implanted falcate-shaped antenna for high-speed transfer rate achieving impedance bandwidth 1.2978 GHz. Proposed antenna is useful for transferring 54 mbps (802.11g) and 600 mbps (802.11n), theoretically, for particular usage in biotelemetry.

In this paper, a strategy to design implantable microstrip antenna used in biomedical telemetry has been suggested. A skin-implanted multilayer microstrip antenna containing ground, and meandered lower and upper radiating patch covered with a superstrate layer has been designed and simulated. A material with high permittivity such as Rogers 3010 has been used for substrate and superstrate layer. The volume of proposed antenna is 230 mm3. The size of proposed MSA is small enough to implant into human head-scalp. The designed antenna is resonating in the MICS (402–405 MHz) band and the 10 dB bandwidth is 23 MHz. The return loss is found as −18.274 dB at 402 MHz.

Abstract In this paper, we discussed the design restraint for designing implantable microstrip antenna (MSA) for body centric communication. We suggested an approach to design implantable MSA used for body centric communication. We also reported a multilayer MSA for medical implant communication services (MICS) band. A superstrate layer was kept to make certain the biocompatibility of the implanted antenna. The size of proposed MSA was small enough to implant into human head-scalp. Further the return loss characteristics for three different superstrate materials were carried out. We also investigated the return loss characteristics by changing substrate material between two radiating patches in firstly designed antenna for MICS band.

This paper presents the design and performance of a modified pentagonal patch antenna with defective ground plane. A pentagonal slot is inserted in the pentagonal patch and slot loaded ground through optimized dimensions is used in the antenna to resonate it at dual frequency. The geometry operates at two resonant frequencies (2.5 GHz and 5.58 GHz) and offers impedance bandwidth of 864 MHz and 554 MHz in the two bands of interest. The proposed antenna covers the lower band (2.45 to 2.484/2.495 to 2.695 GHz) and upper band (5.15 to 5.825 GHz/5.25 to 5.85 GHz) allocated for Wi-Max and WLAN communication systems.
