Abstract:
1. An apparatus that facilitates wireless communications, comprising a microstrip antenna with at least one dipole element with at least one radio frequency (RF) gap that allows the dipole element to resonate at more than one frequency, further comprising: a first microstrip feedline on a first side of a dielectric material; a second microstrip feedline on a second side of the dielectric material; a first dipole element physically connected to the first microstrip; a second dipole element physically connected to the second microstrip oriented with respect to the first dipole element to form a first dipole; a third dipole element on the first side of the dielectric material linearly displaced from the first dipole element in a direction parallel to the orientation of the first dipole wherein the displacement creates a gap between the first dipole element and the third dipole element; and a fourth dipole element on the second side of the dielectric material linearly displaced from the second dipole element in a direction parallel to the orientation of the first dipole and opposite of the direction of displacement of the third dipole element from the first dipole element wherein the displacement creates a gap between the second dipole element and the fourth dipole element; wherein the gaps between the first and third dipole elements and the second and fourth dipole elements are sized such that longer wavelengths traverse the gap as if the gap were short circuited and shorter wavelengths are inhibited from crossing the gaps as if the gaps created an open circuit thereby forming dipole elements of the third dipole having a corresponding dipole wavelength longer than that of the first dipole.
