## Abstract Two types of cavity‐backed slot (CBS) antennas fed by a microstrip line and operating at 5.8 GHz are described in this letter. One is a broadband linearly polarized CBS antenna, which can provide 34% bandwidth for a 10‐dB return loss. The other is a circularly polarized dual T‐shape CBS

Abstract
A novel, folded, capacitive‐fed microstrip antenna with a length of λ/3 and placed over a cavity backing is proposed. Compared to the small rectangular patch antenna of Luk, our proposed antenna has a large impedance bandwidth of 20.1%. The cross‐polarization level is ∼−17 dB. © 2001 John Wiley & Sons, Inc.

## Abstract Slot antennas with a backing cavity for unidirectional radiation are investigated with the aim of achieving a thin structure capable of reasonably broadband operation. By tuning together the slot length and the cavity cross‐section, a very low‐profile cavity‐backed slot (CBS) is demonst
The resonant frequency of a circular patch antenna with and without circular cavity is measured. The patch miniaturization in the presence of the cavity is proved. Different methods of reducing resonant frequencies and broadening bandwidth without significantly reducing antenna gain are presented. C
## Abstract In this letter, we experimentally study a T and a shunt‐stub‐shaped microstrip‐fed slot antenna backed by a ground plane. The proposed antenna has a frequency bandwidth of approximately 54% for __S__~11~≤−10 dB, centered around 2.5 GHz, with relatively good pattern characteristics. © 20
## Abstract In this paper, the regular microstrip dipole antenna shape is modified by adding upper and lower triangular patches, which makes it look like a rhombus. The rhombus shape is chosen because of its wideband characteristics over the rectangular one. The presented antenna provides a wide ba
