Dual-frequency planar antennas can substitute large bandwidth patch antennas, where there is a requirement for large bandwidth to cover two separate transmit receive bands. In this paper a novel single-feed, single layer, double-band, compact short loaded patch antenna is studied theoretically and experimentally. Besides the compactness, this design provides, dual frequency operation with a small frequency ratio of 1.3 between the two resonant bands. Various radiation characteristics are simulated as well as experimentally studied and good concurrence is observed between the simulated and measured results

Low Profile

Patch antenna is a low-profile antenna that has a number of advantages, low cost, light weight,easy to feed and their attractive radiation characteristics. For aWiMAX communication system, a microstrip patch antenna which operates at 2.76 GHz frequency band was presented in this work. The hybrid system solar cell antenna allows energy recovery as well as RF Transmission. A simulation process, withMATLAB, is used to determine the electrical power collected by the studied system as a photovoltaic cell. As a antenna, parameters such as gain, directivity, radiation pattern and radiated power were studied. Simulation results, showed a resonance frequency of the antenna at 2.76 GHz with an effective return loss of -18.64dB and a gain of 6.58dBi. Thereafter, an optical rectenna based on a solar cell antenna was proposed and studied.

The Impact

A low profile pentagonal shaped monopole antenna is designed and presented for wearable applications. The main objective of this paper is to design a miniaturized ultrawide band monopole planar antenna which can work efficiently in free space but also on the surface of the human body. The impact of human tissues on antenna performance is explained using the proposed pentagonal monopole antenna. The antenna is designed with a pentagonal radiator and a matched feed line of 50 ohm and square slots are integrated on defected ground of FR4 substrate with a size of 15 mm × 25 mm to achieve ultrawide band (UWB) performance in free space and human proximity. This overall design will enhance the antenna performance with wide bandwidth ranging from 2.9 GHz to 11 GHz. Specific absorption rate (SAR) of the proposed antenna on dispersive phantom model is also measured to observe the exposure of electromagnetic energy on human tissues. The simulated and measured results of the proposed antenna exhibit wide bandwidth and radiation characteristics in both free space and human proximity.
