Wireless electronic communication devices, in particular, mobile phones
Embodiments of the present invention provide a wireless electronic communication device, in particular a mobile phone, including a transceiver, a display, a keyboard, an antenna to be used with GSM 2G 800/900/1800/1900 MHz radio frequencies. The antenna is mounted in a antenna socket inside a casing, wherein the antenna socket is made in the form of a notch at the back of the casing and vertical walls of the notch being spatially shaped, preferably along a wavy serrated line. The ratio of a circumferential length of the wavy edge line (Lz) to a length of the inner contour of the notch (L) satisfies the following relationship: Lz/L>1.4, wherein Lz is the circumferential length of the wavy edge line and L is the length of the inner contour of the antenna socket notch.
1. A wireless electronic communications device, in particular a mobile phone, comprising a transceiver, a display, a keyboard, and an antenna to be used with GSM 2G 800/900/1800/1900 MHz radio frequencies, wherein the antenna is mounted in an antenna socket inside a casing, wherein the antenna socket is made in the form of a notch at the back of the casing and vertical walls of the notch being spatially shaped, preferably along a wavy serrated line, wherein the ratio of a circumferential length of the wavy edge line (Lz) to a length of an inner contour of the notch (L) undergoes the relationship:
Lz/L> 1.4, and
wherein:
Lz is the circumferential length of the wavy edge line, and
