CIRCULAR POLARIZED ANTENNA, SEMICONDUCTOR MODULE, AND WIRELESS COMMUNICATION DEVICE
First Claim
1. A circular polarized antenna comprising:
- a conductor ground plate that is formed with an opening;
first and second monopole conductor elements that are formed in L-shape having substantially the same length, the first and second monopole conductor elements being respectively connected to the conductor ground plate at first and second connection points; and
a feed point provided at one of the first and second connection points,wherein the first and second monopole conductor elements are arranged to be substantially orthogonal to each other, and open ends of the respective first and second monopole conductor elements are arranged to be adjacent to each other,wherein a first part and a second part of the antenna are configured to be symmetrical with respect to a straight line passing between the open ends of the first and second monopole conductor elements, the straight line being substantially perpendicular to a line connecting the first and second connection points,wherein the first part includes;
(1) a first half of the conductor ground plate formed on one side of the straight line including the first monopole conductor element; and
(2) the first monopole conductor element, andwherein the second part includes;
(3) a second half of the conductor ground plate formed on the other side of the straight line including the second monopole conductor element; and
(4) the second monopole conductor element.

10. A circular polarized antenna comprising:
-
a conductor ground plate with an opening and including a first plate and a second plate being symmetrical with respect to a straight line passing a center of the opening, the first plate having a first connection point and the second plate having a second connection point, a line connecting the first and second connection points being substantially perpendicular to the straight line; first and second monopole conductor elements that are formed in L-shape having substantially the same length and being disposed symmetrically with respect to the straight line, the first monopole conductor element being connected to the first plate at the first connection point and the second monopole conductor element being connected to the second plate at the second connection point; and a feed point provided at one of the first and second connection points, wherein the first and second monopole conductor elements are arranged to be substantially orthogonal to each other, and open ends of the respective first and second monopole conductor elements are arranged to be adjacent to each other.
