A low profile monopolar patch antenna with conical beam radiation pattern and high gain performance is presented in this paper. The antenna has a simple structure which consists of a monopolar patch, a ground and a set of shorting pins. To enhance the gain performance, the antenna is designed to operate with TM03 mode and TM04 mode. The proposed antenna operates from 2.41 to 2.51 GHz for the VSWR...
A compact monopolar patch antenna is presented in this paper. The antenna has a wide bandwidth and a monopole-like radiation pattern. To reduce the whole size of the antenna, a substrate with high dielectric constant is adopted. Besides, three types of shorting pins and a triangle slot are added to the patch to widen the impedance bandwidth. The proposed antenna operates from 2.29 to 2.59 GHz for...
A novel differential-fed patch antenna (DFPA) is proposed in this letter. Based on a capacitance coupling feed, an impedance bandwidth (SWR<2) of 102% has been obtained. The cross-polarization is less than −15dB across the operating bandwidth because of the differential-fed.
A multilayer structure patch antenna is presented in the letter. The structure of the antenna is nearly the same with the traditional microstrip patch antenna except the feeding method. By using L-probe and multilayer structure, it has a wide impedance bandwidth (SWR<2) of 98.4%. The gain of the antenna is around 6dBi across the operating bandwidth.
