<p>PROBLEM TO BE SOLVED: To provide a transmission and reception unit capable of improving antenna gain by making the electrical length of a ground conductor connected to the ground end of an antenna long. SOLUTION: This transmission and reception unit can obtain the electrical length L ofλ/4 length, improves the antenna gain and provides satisfactory transmission and reception sensitivities even when the transmission and reception unit is made small in such a manner that a first corner part 20 of a cover 14 located in the vicinity of the transmission and reception ends 7 and 8 and the ground end 9 of the antenna 4 or a part near the corner part 20 is soldered to a wiring pattern 2c for nongrounding to make the electrical length L of the ground conductor from the ground end 9 long.</p> |
