An antenna structure has a substrate, having a first-side surface and a second-side surface. A first antenna substructure on the first-side surface has a first straight metal line and a second straight metal line. The second straight metal line joins to the first straight metal line, and is substantially perpendicular to the first straight metal line. A second antenna substructure disposed on the second-side surface has a metal plate, serving as a ground, wherein the first straight metal line is overlapping with the metal plate. An L-shape metal line protrudes from the metal plate, wherein a portion of the L-shape metal line is parallel and overlapping with the second straight metal line, and a portion of the L-shape metal line is parallel to the first straight metal line without overlapping.

Dual band patch antenna

An antenna on a printed circuit board (PCB) with a compensating capacitor. The antenna has a radiator disposed over a first surface of the PCB. Wherein the radiator includes a signal feeding section and a tuning section coupled together at a joint. The tuning section includes a bending portion. Also and, a ground layer with or without a protuding portion is disposed on a second surface of the PCB, wherein the bending portion of the tuning section is overlapping with the ground layer to form the compensating capacitor. In addition, the radiator can also have a short circuit stub section, electrically coupled to the ground layer.

Antenna with printed compensating capacitor

A layout of a wireless communication circuit on a printed circuit board (PCB), which is a rectangular board wherein a first side is a Y-axis and a second side is an X-axis. The layout has a first antenna located at a corner between the first side and the second side. An antenna switch and a first filter are located at middle y-coordinate and a X-coordinate. A RF integrated circuit (RFIC) is located after the first filter. A first regulator is located near the second side and higher than the RFIC. A media access control (MAC) is located at about a middle y-coordinate and higher than the first regulator. An oscillator is located at a corner between the second side and the third side. A second regulator is located near the fourth side and above the first regulator. A power amplifier is located near the fourth side above the RFIC. A second filter and a transmitting/receiving (T/R) switch are located before the power amplifier. A second antenna is located at a corner between the first side and the fourth side.
