Biosensors are compact miniaturized devices to measure the biologicalsamples based on the molecular structure and convert the sameto electronic signals. The substrate Integrated Waveguide (SIW) cavitybased resonators loaded with a circular cavity can be used as a biosensorin a non invasive manner to detect the biological tissues in the sample with better efficiency and miniaturized structure.The biosensingsamples may vary from proteins to enzymes which has gained ahuge response in the industries likes medical, agriculture, food processingindustry and many more over the decades. The substrate materialof antenna is designed with Rogers RT/Duroid 5870 which has thedielectric constant of 2.33. The Rectangular patch antenna is thenloaded with the SIW vias for an enhanced performance of S parameterfrom -17.21 dB to -44.88dB operating at the X band (8 to 12GHz) frequencies. The microwell made from the Polydimethylsiloxane(PDMS) material is inserted into the patch infrom of circularslot to achieve the biosensing application. The microwell based SIWcavity is then simulated for different diameters of PDMS to improvethe S11 parameter and Voltage standing wave ratio. The fabricatedantenna is tested to work in the TE110 mode at a resonant frequencyof 12.12GHZ with a improved return loss characteristics of -42.45 dB

Se propone y analiza numéricamente un sensor para la caracterización de la permitividad dieléctrica de substancias en la región de las microondas. Para ello, se emplea una antena basada en un anillo resonador rectangular, en un sustrato TMM® 13i. Este es un compuesto cerámico de polímero dieléctrico termoestable con un factor de disipación de 0,0019 a 10 GHz, el cual nos permite obtener un dispositivo altamente resonante a la frecuencia de 2.4 GHz y 5 GHz. Se emplea el método anillo resonador con un capilar de vidrio pyrex en el centro para interrogar las características eléctricas de este sensor tales como la permitividad, permeabilidad y conductividad. Los resultados obtenidos revelan que el sensor propuesto presenta una sensibilidad de desplazamiento en la frecuencia fundamental, cuando este es empleado en la caracterización de muestras cuya permitividad está dentro del rango 1, a 32.5. Adicionalmente este presenta un tamaño compacto, pues solo mide 42 mm x 46 mm. Además, fueron indagados de manera simulada algunos metales pesados que se pueden encontrar en el medio ambiente. Los resultados obtenidos nos permiten evidenciar que el sensor propuesto resulta ser una alternativa interesante debido a que su fabricación es simple y económica. También, este puede ser fácilmente integrado en redes de sensado inalámbrico, las cuales son de amplio interés a nivel industrial ya que puede ser fácilmente integrado con tecnologías emergentes como internet de las cosas.
