The sensing cycle control module  255  may avoid a noise signal induced through a specific frequency band (e.g., about 0.7 GHz to 6 GHz). The sensing cycle control module  255  may be configured to avoid the noise signal associated with the time domain related to the first wireless transmission signal of the first antenna  210  or the capacitance change amount (e.g., the unit time change value of the capacitance) through the first signal path S 1 .

Based on the frequency band information with the noise component transmitted in real time from the processor  260  through the sensing parameter adjusting unit  254 , the sensor module  250  may remove a noise signal not removed through the first filter  245  through the second filter  256  by adjusting at least one sensing parameter (e.g. a filtering setpoint, a sensing period, or a sensing frequency). 
     Signals including a ripple in the frequency band information having a noise component may generate a ghost grip. The sensor module  250 , varying the sensing frequency or the sensing period by using the sensing parameter adjuster  254  or the second filter  256  according to frequency band information having a noise component transmitted in real time from the processor  260 , may remove noise related to the ripple signal. 
     Referring to  FIG. 4 , when the user of the electronic device  200  contacts (e.g., grips or touches) the first antenna  210 , a unit time change value of the capacitance of the first antenna  210  may be changed (e.g., C 1 , C 2 ). The unit time change value of the capacitance may be changed over a period of, for example, several tens to several hundreds of milliseconds (msec). 
     Referring to  FIG. 5 , when the user of the electronic device  200  contacts (e.g., grips or touches) the first antenna  210 , the noise signal (e.g., n 1 , n 2 , and/or n 3 ) included in the first wireless transmission signal of the first antenna  210  may represent a unit time change value (or amount of change) of capacitance for a time of several tens of nanoseconds (nsec).

For example, the processor  260  of the electronic device  200 , using a window function of about 20 msec, may remove the generated grip signal by the second filter  256  due to a unit time change value (or amount of change) of the capacitance that appears without the presence of a continuous value within about 20 msec and this change.

     In step  810 , the processor  260  monitors the contact state of the first antenna  210 . 
     When the first antenna  210  comes into contact with the body of a user of the electronic device  200 , the processor  260  may receive a sensing signal related to the unit time change value (or change amount) of the capacitance of the first antenna  210  according to the contact through the sensor module  250  disposed on the second PCB  240 . 
     In step  820 , the processor  260  configures a filtering setting value or a sensing period of the sensor module  250  (e.g., the second filter  256 ) based on the frequency band information in which the communication is made through the first antenna  210 . 
     The second filter  256  may adjust the filtering setting value or the sensing period (or sensing frequency) based on the frequency band information transmitted in real time through the processor  260 . 
     In step  830 , the processor  260  determines whether a body part of the user of the electronic device  200  has been in contact with the first antenna  210 .

Also, based on the received capacitance change value (or change amount) per unit time, the processor  260  may determine whether the first antenna  210  is touched (gripped or touched) by the user. 
     In step  840 , if the first antenna  210  is touched (grip or touch) by the user of the electronic device  200 , the first filter  245  or the second filter  256  is used to remove a noise signal from a sensing signal related to a first wireless reception signal received through the first antenna  210  or a unit time change value (or amount of change) of capacitance. 
     In step  850 , the processor  260  controls the communication module  244  to control a transmission power of a signal that is transmitted through the first antenna  210 .
