A dual-frequency patch antenna includes a ground plane, an inside radiator, and an outside radiator. The inside radiator is configured as a region with a periphery, along which is a series of first protrusions separated by first grooves. The outside radiator is configured as a ring with an...
Dual-frequency patch antennas may provide an alternative to large-bandwidth planar antennas, in applications in which large bandwidth is really needed for operating at two separate transmit-receive bands. When the two operating frequencies are far apart, a dual-frequency patch structure can be conceiv...

摘要: A small dual-frequency printed antenna based on a stacked shorted patch configuration with a common feed is presented. The antenna allows for relatively independent control of the two resonant frequencies. The new concept is demonstrated and the measured performance of the radiator is given....
It is found that rectangular antenna having an appropriate size of rectangular notch resonates at two different frequencies and also provides much improved bandwidth. On the introduction of an air gap of 1.5 mm between the dielectric layers, this antenna resonates only at a single frequency but ...
A dual-frequency dual-circularly polarised patch antenna with wide beamwidth is proposed. The two-layer structure comprises circular patches with offset circular slots connected to rectangular slots. They provide orthogonal perturbations realising RHCP and LHCP for the lower and upper bands, respectively....

dual-frequency; patch antenna Abstract Design of a rectangular coplanar patch antenna for obtaining dual-frequency operation using a coplanar waveguide with ground (CPWG) feed is presented. This is achieved by introducing an CPWG feed line attaching on the diagonal of the patch. Details of the pro...
