Compact Multi-slotted Printed Antenna for Ultra-Wideband Applications in Medical Telemetry

In this study, the two designs of the compact microstrip patch antennas, exhibiting ultra wideband characteristics are presented. The design offers an overall bandwidth of 4.7 and 5.2 GHz with a return loss of −35dB and −40 dB, respectively. The presented designs of the antennas are targeted for applications in medical telemetry. Geometrical optimizations for the slotted rectangular patch antenna loaded with notches are carried out to enhance the bandwidth over the ultra wideband. Unlike the conventional way, the microstrip patch antenna is optimized by considering an infinite substrate. The effect of finite substrate on the bandwidth of the microstrip patch is investigated leading to better results in terms of simplicity, compact size, and bandwidth. Also, it is perceived that the partial ground plane, which is incorporated, improves the antenna’s bandwidth drastically and also the reflection coefficient. The prototype of the two presented designs is formulated by creating notches with three slots naming it to be MPA1, and the other one without slots and with only notches naming it to be MPA2 for observing the relative effect of slots and the partial ground plane on the bandwidth. A very close agreement is confirmed between the simulated and the experimental values of the reflection coefficient and the bandwidth. The maximum percentage bandwidth of 85% is attained in the case of MPA2, while a maximum gain of 2.39 dBi is achieved for MPA1, which offers flexibility to manufacturers for use.

New Design Approach of a “2.4 GHz” Slotted Rectangular Patch Antenna with a Wideband Harmonic Suppression

The designing of an antenna with a wideband harmonic suppression will lead to enhance the overall antenna performance efficiency as well as neglecting electromagnetic noises. A “defective ground superimposing” or a Y-slot construct confederated with a ring hopefully meets an effective approach that is exploited in removing high level of harmonics in the design process. A “2.4 GHz” rectangular U-slot microstrip patch antenna with an active antenna radiators and harmonic suppression grid has been presented. The paper focuses on the geometrical of active integration antennas to achieve efficient filtering and easy attenuation of unwanted harmonics. Further, an embedded empirical antenna with a high-order harmonic suppression has been suggested. This is followed by a “complementary opening recoiled construct cell”. The proposed approach was developed to control the antenna harmonics at center frequency of " $$2.4 \;{\text{GHz}}$$ ." The simulation sketches show that the reflection coefficient of multiple harmonics had an effective suppression up to 3.2 dB without any effect on the resonant frequency. The radiation patterns at high suppression levels of harmonics are within the range (13.92–15.2 dB) for both E-plane and H-plane. Further, the designed antenna bandwidth at the resonant frequency is $$\left( {85\;{\text{MHz}}} \right)$$ . Finally, the proposed antenna with $${\text{DGS}}$$ had return losses and antenna gain of $$\left( { - 23.15 \;{\text{dB}};\;8.25\;{\text{dB}}} \right),$$ respectively.
