These days most of the research work in the area of filter-antenna design is focused on having high quality factor for certain frequency band. These type of filter-antennas are difficult to design as the design engineers are required to have low quality factor for the radiating band of frequency. Hence a precise value of $$Q$$-factor is required to understand the radiating and filtering properties of filter-antennas. Filter-antennas are single port devices as the second port is considered as radiating port. Return loss is used, in order to yield $$Q$$-factor through calculations for such devices. However, the conventional method for calculating $$Q$$-factor found to be inaccurate in most of the low $$Q$$-factor cases. This paper proposes a method that out performs the conventional method of calculating $$Q$$-factor. Non-ideal fabrication process is also discussed for accurate evaluation of $$Q$$-factor. Experimental results show that proposed method can be employed to calculate $$Q$$-factor with reasonable accuracy for simulated and measured results. |
